Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497670, here are decompositions:
- 3 + 31497667 = 31497670
- 101 + 31497569 = 31497670
- 179 + 31497491 = 31497670
- 227 + 31497443 = 31497670
- 311 + 31497359 = 31497670
- 317 + 31497353 = 31497670
- 383 + 31497287 = 31497670
- 419 + 31497251 = 31497670
Showing the first eight; more decompositions exist.
