Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7662, here are decompositions:

13 + 7649 = 7662
19 + 7643 = 7662
23 + 7639 = 7662
41 + 7621 = 7662
59 + 7603 = 7662
71 + 7591 = 7662
73 + 7589 = 7662
79 + 7583 = 7662

Showing the first eight; more decompositions exist.
