Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7758, here are decompositions:
- 5 + 7753 = 7758
- 17 + 7741 = 7758
- 31 + 7727 = 7758
- 41 + 7717 = 7758
- 59 + 7699 = 7758
- 67 + 7691 = 7758
- 71 + 7687 = 7758
- 89 + 7669 = 7758
Showing the first eight; more decompositions exist.
