Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139924, here are decompositions:
- 3 + 139921 = 139924
- 17 + 139907 = 139924
- 23 + 139901 = 139924
- 41 + 139883 = 139924
- 53 + 139871 = 139924
- 137 + 139787 = 139924
- 227 + 139697 = 139924
- 263 + 139661 = 139924
Showing the first eight; more decompositions exist.
