Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86590, here are decompositions:
- 3 + 86587 = 86590
- 11 + 86579 = 86590
- 17 + 86573 = 86590
- 29 + 86561 = 86590
- 59 + 86531 = 86590
- 89 + 86501 = 86590
- 113 + 86477 = 86590
- 137 + 86453 = 86590
Showing the first eight; more decompositions exist.
