Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72288, here are decompositions:
- 11 + 72277 = 72288
- 17 + 72271 = 72288
- 19 + 72269 = 72288
- 37 + 72251 = 72288
- 59 + 72229 = 72288
- 61 + 72227 = 72288
- 67 + 72221 = 72288
- 127 + 72161 = 72288
Showing the first eight; more decompositions exist.
