Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82712, here are decompositions:
- 13 + 82699 = 82712
- 61 + 82651 = 82712
- 79 + 82633 = 82712
- 103 + 82609 = 82712
- 151 + 82561 = 82712
- 163 + 82549 = 82712
- 181 + 82531 = 82712
- 229 + 82483 = 82712
Showing the first eight; more decompositions exist.
