Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145462, here are decompositions:
- 3 + 145459 = 145462
- 11 + 145451 = 145462
- 29 + 145433 = 145462
- 71 + 145391 = 145462
- 101 + 145361 = 145462
- 113 + 145349 = 145462
- 173 + 145289 = 145462
- 179 + 145283 = 145462
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 145,462 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 145462 first appears in π at position 825,435 of the decimal expansion (the 825,435ordinal-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.
