Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124228, here are decompositions:
- 29 + 124199 = 124228
- 47 + 124181 = 124228
- 89 + 124139 = 124228
- 107 + 124121 = 124228
- 131 + 124097 = 124228
- 227 + 124001 = 124228
- 239 + 123989 = 124228
- 317 + 123911 = 124228
Showing the first eight; more decompositions exist.
