Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7622, here are decompositions:

19 + 7603 = 7622
31 + 7591 = 7622
61 + 7561 = 7622
73 + 7549 = 7622
163 + 7459 = 7622
211 + 7411 = 7622
229 + 7393 = 7622
271 + 7351 = 7622

Showing the first eight; more decompositions exist.
