Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7996, here are decompositions:
- 3 + 7993 = 7996
- 47 + 7949 = 7996
- 59 + 7937 = 7996
- 89 + 7907 = 7996
- 113 + 7883 = 7996
- 167 + 7829 = 7996
- 173 + 7823 = 7996
- 179 + 7817 = 7996
Showing the first eight; more decompositions exist.
