Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30630, here are decompositions:

37 + 30593 = 30630
53 + 30577 = 30630
71 + 30559 = 30630
73 + 30557 = 30630
101 + 30529 = 30630
113 + 30517 = 30630
137 + 30493 = 30630
139 + 30491 = 30630

Showing the first eight; more decompositions exist.
