Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489630, here are decompositions:
- 17 + 31489613 = 31489630
- 59 + 31489571 = 31489630
- 89 + 31489541 = 31489630
- 167 + 31489463 = 31489630
- 197 + 31489433 = 31489630
- 239 + 31489391 = 31489630
- 281 + 31489349 = 31489630
- 383 + 31489247 = 31489630
Showing the first eight; more decompositions exist.
