Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29712, here are decompositions:
- 29 + 29683 = 29712
- 41 + 29671 = 29712
- 43 + 29669 = 29712
- 71 + 29641 = 29712
- 79 + 29633 = 29712
- 83 + 29629 = 29712
- 101 + 29611 = 29712
- 113 + 29599 = 29712
Showing the first eight; more decompositions exist.
