Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86520, here are decompositions:
- 11 + 86509 = 86520
- 19 + 86501 = 86520
- 29 + 86491 = 86520
- 43 + 86477 = 86520
- 53 + 86467 = 86520
- 59 + 86461 = 86520
- 67 + 86453 = 86520
- 79 + 86441 = 86520
Showing the first eight; more decompositions exist.
