Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145464, here are decompositions:
- 5 + 145459 = 145464
- 13 + 145451 = 145464
- 23 + 145441 = 145464
- 31 + 145433 = 145464
- 41 + 145423 = 145464
- 47 + 145417 = 145464
- 73 + 145391 = 145464
- 83 + 145381 = 145464
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 145,464 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 145464 first appears in π at position 90,652 of the decimal expansion (the 90,652ordinal-suffix:nd 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.
