Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71690, here are decompositions:
- 19 + 71671 = 71690
- 43 + 71647 = 71690
- 97 + 71593 = 71690
- 127 + 71563 = 71690
- 139 + 71551 = 71690
- 163 + 71527 = 71690
- 211 + 71479 = 71690
- 271 + 71419 = 71690
Showing the first eight; more decompositions exist.
