Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966720, here are decompositions:
- 43 + 966677 = 966720
- 59 + 966661 = 966720
- 61 + 966659 = 966720
- 67 + 966653 = 966720
- 89 + 966631 = 966720
- 101 + 966619 = 966720
- 103 + 966617 = 966720
- 107 + 966613 = 966720
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 966,720 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 966720 first appears in π at position 33,073 of the decimal expansion (the 33,073ordinal-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.
