Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47712, here are decompositions:
- 11 + 47701 = 47712
- 13 + 47699 = 47712
- 31 + 47681 = 47712
- 53 + 47659 = 47712
- 59 + 47653 = 47712
- 73 + 47639 = 47712
- 83 + 47629 = 47712
- 89 + 47623 = 47712
Showing the first eight; more decompositions exist.
