Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122736, here are decompositions:
- 17 + 122719 = 122736
- 43 + 122693 = 122736
- 73 + 122663 = 122736
- 83 + 122653 = 122736
- 127 + 122609 = 122736
- 137 + 122599 = 122736
- 139 + 122597 = 122736
- 157 + 122579 = 122736
Showing the first eight; more decompositions exist.
