Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539276, here are decompositions:
- 5 + 31539271 = 31539276
- 47 + 31539229 = 31539276
- 113 + 31539163 = 31539276
- 193 + 31539083 = 31539276
- 229 + 31539047 = 31539276
- 233 + 31539043 = 31539276
- 269 + 31539007 = 31539276
- 389 + 31538887 = 31539276
Showing the first eight; more decompositions exist.
