Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139966, here are decompositions:
- 23 + 139943 = 139966
- 59 + 139907 = 139966
- 83 + 139883 = 139966
- 179 + 139787 = 139966
- 227 + 139739 = 139966
- 257 + 139709 = 139966
- 263 + 139703 = 139966
- 269 + 139697 = 139966
Showing the first eight; more decompositions exist.
