Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615504, here are decompositions:
- 101 + 31615403 = 31615504
- 113 + 31615391 = 31615504
- 191 + 31615313 = 31615504
- 293 + 31615211 = 31615504
- 311 + 31615193 = 31615504
- 317 + 31615187 = 31615504
- 443 + 31615061 = 31615504
- 491 + 31615013 = 31615504
Showing the first eight; more decompositions exist.
