Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471576, here are decompositions:
- 53 + 31471523 = 31471576
- 107 + 31471469 = 31471576
- 137 + 31471439 = 31471576
- 179 + 31471397 = 31471576
- 359 + 31471217 = 31471576
- 467 + 31471109 = 31471576
- 569 + 31471007 = 31471576
- 599 + 31470977 = 31471576
Showing the first eight; more decompositions exist.
