Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527528, here are decompositions:
- 5 + 31527523 = 31527528
- 7 + 31527521 = 31527528
- 29 + 31527499 = 31527528
- 31 + 31527497 = 31527528
- 37 + 31527491 = 31527528
- 47 + 31527481 = 31527528
- 139 + 31527389 = 31527528
- 211 + 31527317 = 31527528
Showing the first eight; more decompositions exist.
