Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11630, here are decompositions:

13 + 11617 = 11630
37 + 11593 = 11630
43 + 11587 = 11630
79 + 11551 = 11630
103 + 11527 = 11630
127 + 11503 = 11630
139 + 11491 = 11630
163 + 11467 = 11630

Showing the first eight; more decompositions exist.
