Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155462, here are decompositions:
- 19 + 155443 = 155462
- 79 + 155383 = 155462
- 163 + 155299 = 155462
- 193 + 155269 = 155462
- 211 + 155251 = 155462
- 271 + 155191 = 155462
- 379 + 155083 = 155462
- 613 + 154849 = 155462
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 155,462 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 155462 first appears in π at position 371,579 of the decimal expansion (the 371,579ordinal-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.
