Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130630, here are decompositions:

11 + 130619 = 130630
41 + 130589 = 130630
83 + 130547 = 130630
107 + 130523 = 130630
113 + 130517 = 130630
173 + 130457 = 130630
191 + 130439 = 130630
251 + 130379 = 130630

Showing the first eight; more decompositions exist.
