Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539376, here are decompositions:
- 23 + 31539353 = 31539376
- 47 + 31539329 = 31539376
- 233 + 31539143 = 31539376
- 293 + 31539083 = 31539376
- 389 + 31538987 = 31539376
- 569 + 31538807 = 31539376
- 587 + 31538789 = 31539376
- 647 + 31538729 = 31539376
Showing the first eight; more decompositions exist.
