Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 464128, here are decompositions:
- 47 + 464081 = 464128
- 59 + 464069 = 464128
- 107 + 464021 = 464128
- 179 + 463949 = 464128
- 239 + 463889 = 464128
- 347 + 463781 = 464128
- 449 + 463679 = 464128
- 479 + 463649 = 464128
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 464,128 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 464128 first appears in π at position 648,946 of the decimal expansion (the 648,946ordinal-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.
