Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31854, here are decompositions:
- 5 + 31849 = 31854
- 7 + 31847 = 31854
- 37 + 31817 = 31854
- 61 + 31793 = 31854
- 83 + 31771 = 31854
- 103 + 31751 = 31854
- 113 + 31741 = 31854
- 127 + 31727 = 31854
Showing the first eight; more decompositions exist.
