Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126928, here are decompositions:
- 5 + 126923 = 126928
- 71 + 126857 = 126928
- 89 + 126839 = 126928
- 101 + 126827 = 126928
- 167 + 126761 = 126928
- 317 + 126611 = 126928
- 467 + 126461 = 126928
- 569 + 126359 = 126928
Showing the first eight; more decompositions exist.
