Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545664, here are decompositions:
- 13 + 545651 = 545664
- 17 + 545647 = 545664
- 23 + 545641 = 545664
- 43 + 545621 = 545664
- 47 + 545617 = 545664
- 113 + 545551 = 545664
- 131 + 545533 = 545664
- 137 + 545527 = 545664
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 545,664 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 545664 first appears in π at position 157,893 of the decimal expansion (the 157,893ordinal-suffix:rd 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.
