Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28726, here are decompositions:
- 3 + 28723 = 28726
- 23 + 28703 = 28726
- 29 + 28697 = 28726
- 83 + 28643 = 28726
- 107 + 28619 = 28726
- 167 + 28559 = 28726
- 179 + 28547 = 28726
- 227 + 28499 = 28726
Showing the first eight; more decompositions exist.

The digit sequence 28726 first appears in π at position 106,975 of the decimal expansion (the 106,975ordinal-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.
