Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139618, here are decompositions:
- 29 + 139589 = 139618
- 47 + 139571 = 139618
- 71 + 139547 = 139618
- 107 + 139511 = 139618
- 131 + 139487 = 139618
- 179 + 139439 = 139618
- 251 + 139367 = 139618
- 257 + 139361 = 139618
Showing the first eight; more decompositions exist.
