Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139528, here are decompositions:
- 17 + 139511 = 139528
- 41 + 139487 = 139528
- 71 + 139457 = 139528
- 89 + 139439 = 139528
- 131 + 139397 = 139528
- 167 + 139361 = 139528
- 227 + 139301 = 139528
- 359 + 139169 = 139528
Showing the first eight; more decompositions exist.
