Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30626, here are decompositions:

67 + 30559 = 30626
73 + 30553 = 30626
97 + 30529 = 30626
109 + 30517 = 30626
157 + 30469 = 30626
199 + 30427 = 30626
223 + 30403 = 30626
307 + 30319 = 30626

Showing the first eight; more decompositions exist.
