Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545716, here are decompositions:
- 3 + 31545713 = 31545716
- 109 + 31545607 = 31545716
- 229 + 31545487 = 31545716
- 277 + 31545439 = 31545716
- 337 + 31545379 = 31545716
- 373 + 31545343 = 31545716
- 619 + 31545097 = 31545716
- 859 + 31544857 = 31545716
Showing the first eight; more decompositions exist.
