Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7642, here are decompositions:

3 + 7639 = 7642
53 + 7589 = 7642
59 + 7583 = 7642
83 + 7559 = 7642
101 + 7541 = 7642
113 + 7529 = 7642
191 + 7451 = 7642
293 + 7349 = 7642

Showing the first eight; more decompositions exist.
