Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7936, here are decompositions:
- 3 + 7933 = 7936
- 17 + 7919 = 7936
- 29 + 7907 = 7936
- 53 + 7883 = 7936
- 59 + 7877 = 7936
- 83 + 7853 = 7936
- 107 + 7829 = 7936
- 113 + 7823 = 7936
Showing the first eight; more decompositions exist.
