Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540866, here are decompositions:
- 29 + 31540837 = 31540866
- 43 + 31540823 = 31540866
- 53 + 31540813 = 31540866
- 79 + 31540787 = 31540866
- 83 + 31540783 = 31540866
- 139 + 31540727 = 31540866
- 157 + 31540709 = 31540866
- 167 + 31540699 = 31540866
Showing the first eight; more decompositions exist.
