Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7722, here are decompositions:

5 + 7717 = 7722
19 + 7703 = 7722
23 + 7699 = 7722
31 + 7691 = 7722
41 + 7681 = 7722
53 + 7669 = 7722
73 + 7649 = 7722
79 + 7643 = 7722

Showing the first eight; more decompositions exist.
