Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30588, here are decompositions:

11 + 30577 = 30588
29 + 30559 = 30588
31 + 30557 = 30588
59 + 30529 = 30588
71 + 30517 = 30588
79 + 30509 = 30588
97 + 30491 = 30588
139 + 30449 = 30588

Showing the first eight; more decompositions exist.
