Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527716, here are decompositions:
- 7 + 31527709 = 31527716
- 13 + 31527703 = 31527716
- 19 + 31527697 = 31527716
- 139 + 31527577 = 31527716
- 193 + 31527523 = 31527716
- 373 + 31527343 = 31527716
- 439 + 31527277 = 31527716
- 463 + 31527253 = 31527716
Showing the first eight; more decompositions exist.
