Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128696, here are decompositions:
- 3 + 128693 = 128696
- 13 + 128683 = 128696
- 19 + 128677 = 128696
- 37 + 128659 = 128696
- 67 + 128629 = 128696
- 97 + 128599 = 128696
- 223 + 128473 = 128696
- 229 + 128467 = 128696
Showing the first eight; more decompositions exist.
