Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72336, here are decompositions:
- 23 + 72313 = 72336
- 29 + 72307 = 72336
- 59 + 72277 = 72336
- 67 + 72269 = 72336
- 83 + 72253 = 72336
- 107 + 72229 = 72336
- 109 + 72227 = 72336
- 113 + 72223 = 72336
Showing the first eight; more decompositions exist.
