Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149402, here are decompositions:
- 3 + 149399 = 149402
- 31 + 149371 = 149402
- 61 + 149341 = 149402
- 79 + 149323 = 149402
- 151 + 149251 = 149402
- 163 + 149239 = 149402
- 229 + 149173 = 149402
- 241 + 149161 = 149402
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 149,402 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 149402 first appears in π at position 612,457 of the decimal expansion (the 612,457ordinal-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.
