Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30572, here are decompositions:

13 + 30559 = 30572
19 + 30553 = 30572
43 + 30529 = 30572
79 + 30493 = 30572
103 + 30469 = 30572
181 + 30391 = 30572
313 + 30259 = 30572
331 + 30241 = 30572

Showing the first eight; more decompositions exist.
