Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576850, here are decompositions:
- 7 + 31576843 = 31576850
- 73 + 31576777 = 31576850
- 211 + 31576639 = 31576850
- 271 + 31576579 = 31576850
- 367 + 31576483 = 31576850
- 373 + 31576477 = 31576850
- 397 + 31576453 = 31576850
- 433 + 31576417 = 31576850
Showing the first eight; more decompositions exist.
