Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71822, here are decompositions:
- 13 + 71809 = 71822
- 61 + 71761 = 71822
- 103 + 71719 = 71822
- 109 + 71713 = 71822
- 151 + 71671 = 71822
- 229 + 71593 = 71822
- 271 + 71551 = 71822
- 349 + 71473 = 71822
Showing the first eight; more decompositions exist.
