Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145064, here are decompositions:
- 43 + 145021 = 145064
- 97 + 144967 = 145064
- 103 + 144961 = 145064
- 181 + 144883 = 145064
- 307 + 144757 = 145064
- 313 + 144751 = 145064
- 397 + 144667 = 145064
- 487 + 144577 = 145064
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 145,064 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 145064 first appears in π at position 174,107 of the decimal expansion (the 174,107ordinal-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.
