Goldbach decomposition

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.
