Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541636, here are decompositions:
- 3 + 31541633 = 31541636
- 67 + 31541569 = 31541636
- 73 + 31541563 = 31541636
- 79 + 31541557 = 31541636
- 109 + 31541527 = 31541636
- 127 + 31541509 = 31541636
- 199 + 31541437 = 31541636
- 277 + 31541359 = 31541636
Showing the first eight; more decompositions exist.
