Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477824, here are decompositions:
- 13 + 31477811 = 31477824
- 31 + 31477793 = 31477824
- 43 + 31477781 = 31477824
- 71 + 31477753 = 31477824
- 73 + 31477751 = 31477824
- 101 + 31477723 = 31477824
- 107 + 31477717 = 31477824
- 113 + 31477711 = 31477824
Showing the first eight; more decompositions exist.
