Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486850, here are decompositions:
- 127 + 31486723 = 31486850
- 139 + 31486711 = 31486850
- 193 + 31486657 = 31486850
- 211 + 31486639 = 31486850
- 223 + 31486627 = 31486850
- 313 + 31486537 = 31486850
- 397 + 31486453 = 31486850
- 433 + 31486417 = 31486850
Showing the first eight; more decompositions exist.
