Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546764, here are decompositions:
- 5 + 31546759 = 31546764
- 23 + 31546741 = 31546764
- 43 + 31546721 = 31546764
- 47 + 31546717 = 31546764
- 101 + 31546663 = 31546764
- 103 + 31546661 = 31546764
- 107 + 31546657 = 31546764
- 127 + 31546637 = 31546764
Showing the first eight; more decompositions exist.
