Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28748, here are decompositions:
- 19 + 28729 = 28748
- 37 + 28711 = 28748
- 61 + 28687 = 28748
- 79 + 28669 = 28748
- 127 + 28621 = 28748
- 151 + 28597 = 28748
- 157 + 28591 = 28748
- 199 + 28549 = 28748
Showing the first eight; more decompositions exist.

The digit sequence 28748 first appears in π at position 2,552 of the decimal expansion (the 2,552ordinal-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.
