Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7744, here are decompositions:
- 3 + 7741 = 7744
- 17 + 7727 = 7744
- 41 + 7703 = 7744
- 53 + 7691 = 7744
- 71 + 7673 = 7744
- 101 + 7643 = 7744
- 137 + 7607 = 7744
- 167 + 7577 = 7744
Showing the first eight; more decompositions exist.
