Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72586, here are decompositions:
- 53 + 72533 = 72586
- 83 + 72503 = 72586
- 89 + 72497 = 72586
- 233 + 72353 = 72586
- 317 + 72269 = 72586
- 359 + 72227 = 72586
- 419 + 72167 = 72586
- 509 + 72077 = 72586
Showing the first eight; more decompositions exist.
