Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471442, here are decompositions:
- 3 + 31471439 = 31471442
- 31 + 31471411 = 31471442
- 229 + 31471213 = 31471442
- 271 + 31471171 = 31471442
- 349 + 31471093 = 31471442
- 619 + 31470823 = 31471442
- 643 + 31470799 = 31471442
- 661 + 31470781 = 31471442
Showing the first eight; more decompositions exist.
