Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31760, here are decompositions:
- 19 + 31741 = 31760
- 31 + 31729 = 31760
- 37 + 31723 = 31760
- 61 + 31699 = 31760
- 73 + 31687 = 31760
- 97 + 31663 = 31760
- 103 + 31657 = 31760
- 193 + 31567 = 31760
Showing the first eight; more decompositions exist.
