Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30722, here are decompositions:

19 + 30703 = 30722
61 + 30661 = 30722
73 + 30649 = 30722
79 + 30643 = 30722
163 + 30559 = 30722
193 + 30529 = 30722
229 + 30493 = 30722
331 + 30391 = 30722

Showing the first eight; more decompositions exist.
