Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40712, here are decompositions:
- 3 + 40709 = 40712
- 13 + 40699 = 40712
- 19 + 40693 = 40712
- 73 + 40639 = 40712
- 103 + 40609 = 40712
- 181 + 40531 = 40712
- 193 + 40519 = 40712
- 229 + 40483 = 40712
Showing the first eight; more decompositions exist.
