Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567776, here are decompositions:
- 7 + 31567769 = 31567776
- 47 + 31567729 = 31567776
- 59 + 31567717 = 31567776
- 67 + 31567709 = 31567776
- 83 + 31567693 = 31567776
- 89 + 31567687 = 31567776
- 103 + 31567673 = 31567776
- 127 + 31567649 = 31567776
Showing the first eight; more decompositions exist.
