Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157402, here are decompositions:
- 53 + 157349 = 157402
- 131 + 157271 = 157402
- 149 + 157253 = 157402
- 173 + 157229 = 157402
- 191 + 157211 = 157402
- 239 + 157163 = 157402
- 269 + 157133 = 157402
- 293 + 157109 = 157402
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 157,402 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 157402 first appears in π at position 340,920 of the decimal expansion (the 340,920ordinal-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.
