Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7422, here are decompositions:

5 + 7417 = 7422
11 + 7411 = 7422
29 + 7393 = 7422
53 + 7369 = 7422
71 + 7351 = 7422
73 + 7349 = 7422
89 + 7333 = 7422
101 + 7321 = 7422

Showing the first eight; more decompositions exist.
