Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123562, here are decompositions:

11 + 123551 = 123562
59 + 123503 = 123562
71 + 123491 = 123562
83 + 123479 = 123562
113 + 123449 = 123562
239 + 123323 = 123562
251 + 123311 = 123562
293 + 123269 = 123562

Showing the first eight; more decompositions exist.
