Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163402, here are decompositions:
- 179 + 163223 = 163402
- 191 + 163211 = 163402
- 233 + 163169 = 163402
- 251 + 163151 = 163402
- 293 + 163109 = 163402
- 383 + 163019 = 163402
- 431 + 162971 = 163402
- 521 + 162881 = 163402
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 163,402 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 163402 first appears in π at position 858,270 of the decimal expansion (the 858,270ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
