Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142712, here are decompositions:
- 13 + 142699 = 142712
- 103 + 142609 = 142712
- 139 + 142573 = 142712
- 211 + 142501 = 142712
- 331 + 142381 = 142712
- 523 + 142189 = 142712
- 601 + 142111 = 142712
- 613 + 142099 = 142712
Showing the first eight; more decompositions exist.
