Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118712, here are decompositions:
- 3 + 118709 = 118712
- 31 + 118681 = 118712
- 43 + 118669 = 118712
- 79 + 118633 = 118712
- 109 + 118603 = 118712
- 163 + 118549 = 118712
- 241 + 118471 = 118712
- 283 + 118429 = 118712
Showing the first eight; more decompositions exist.
