Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139570, here are decompositions:
- 23 + 139547 = 139570
- 59 + 139511 = 139570
- 83 + 139487 = 139570
- 113 + 139457 = 139570
- 131 + 139439 = 139570
- 173 + 139397 = 139570
- 227 + 139343 = 139570
- 257 + 139313 = 139570
Showing the first eight; more decompositions exist.
