Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615582, here are decompositions:
- 179 + 31615403 = 31615582
- 191 + 31615391 = 31615582
- 239 + 31615343 = 31615582
- 269 + 31615313 = 31615582
- 353 + 31615229 = 31615582
- 389 + 31615193 = 31615582
- 419 + 31615163 = 31615582
- 521 + 31615061 = 31615582
Showing the first eight; more decompositions exist.
