Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477760, here are decompositions:
- 7 + 31477753 = 31477760
- 31 + 31477729 = 31477760
- 37 + 31477723 = 31477760
- 43 + 31477717 = 31477760
- 103 + 31477657 = 31477760
- 157 + 31477603 = 31477760
- 199 + 31477561 = 31477760
- 211 + 31477549 = 31477760
Showing the first eight; more decompositions exist.
