Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471736, here are decompositions:
- 73 + 31471663 = 31471736
- 97 + 31471639 = 31471736
- 103 + 31471633 = 31471736
- 157 + 31471579 = 31471736
- 349 + 31471387 = 31471736
- 379 + 31471357 = 31471736
- 523 + 31471213 = 31471736
- 613 + 31471123 = 31471736
Showing the first eight; more decompositions exist.
