Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7788, here are decompositions:
- 29 + 7759 = 7788
- 31 + 7757 = 7788
- 47 + 7741 = 7788
- 61 + 7727 = 7788
- 71 + 7717 = 7788
- 89 + 7699 = 7788
- 97 + 7691 = 7788
- 101 + 7687 = 7788
Showing the first eight; more decompositions exist.
