Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7992, here are decompositions:
- 29 + 7963 = 7992
- 41 + 7951 = 7992
- 43 + 7949 = 7992
- 59 + 7933 = 7992
- 73 + 7919 = 7992
- 109 + 7883 = 7992
- 113 + 7879 = 7992
- 139 + 7853 = 7992
Showing the first eight; more decompositions exist.
