Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40670, here are decompositions:
- 31 + 40639 = 40670
- 43 + 40627 = 40670
- 61 + 40609 = 40670
- 73 + 40597 = 40670
- 79 + 40591 = 40670
- 127 + 40543 = 40670
- 139 + 40531 = 40670
- 151 + 40519 = 40670
Showing the first eight; more decompositions exist.
