Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30612, here are decompositions:

19 + 30593 = 30612
53 + 30559 = 30612
59 + 30553 = 30612
73 + 30539 = 30612
83 + 30529 = 30612
103 + 30509 = 30612
163 + 30449 = 30612
181 + 30431 = 30612

Showing the first eight; more decompositions exist.
