Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7956, here are decompositions:
- 5 + 7951 = 7956
- 7 + 7949 = 7956
- 19 + 7937 = 7956
- 23 + 7933 = 7956
- 29 + 7927 = 7956
- 37 + 7919 = 7956
- 73 + 7883 = 7956
- 79 + 7877 = 7956
Showing the first eight; more decompositions exist.
