Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542892, here are decompositions:
- 11 + 31542881 = 31542892
- 83 + 31542809 = 31542892
- 233 + 31542659 = 31542892
- 383 + 31542509 = 31542892
- 569 + 31542323 = 31542892
- 659 + 31542233 = 31542892
- 743 + 31542149 = 31542892
- 809 + 31542083 = 31542892
Showing the first eight; more decompositions exist.
