Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122628, here are decompositions:
- 17 + 122611 = 122628
- 19 + 122609 = 122628
- 29 + 122599 = 122628
- 31 + 122597 = 122628
- 67 + 122561 = 122628
- 71 + 122557 = 122628
- 101 + 122527 = 122628
- 127 + 122501 = 122628
Showing the first eight; more decompositions exist.
