Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145264, here are decompositions:
- 5 + 145259 = 145264
- 11 + 145253 = 145264
- 71 + 145193 = 145264
- 131 + 145133 = 145264
- 173 + 145091 = 145264
- 227 + 145037 = 145264
- 233 + 145031 = 145264
- 257 + 145007 = 145264
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 145,264 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 145264 first appears in π at position 324,018 of the decimal expansion (the 324,018ordinal-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.
