Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539318, here are decompositions:
- 29 + 31539289 = 31539318
- 47 + 31539271 = 31539318
- 89 + 31539229 = 31539318
- 127 + 31539191 = 31539318
- 229 + 31539089 = 31539318
- 257 + 31539061 = 31539318
- 271 + 31539047 = 31539318
- 311 + 31539007 = 31539318
Showing the first eight; more decompositions exist.
