Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139124, here are decompositions:
- 3 + 139121 = 139124
- 103 + 139021 = 139124
- 157 + 138967 = 139124
- 241 + 138883 = 139124
- 283 + 138841 = 139124
- 331 + 138793 = 139124
- 397 + 138727 = 139124
- 463 + 138661 = 139124
Showing the first eight; more decompositions exist.
