Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115638, here are decompositions:

7 + 115631 = 115638
37 + 115601 = 115638
41 + 115597 = 115638
67 + 115571 = 115638
139 + 115499 = 115638
167 + 115471 = 115638
179 + 115459 = 115638
239 + 115399 = 115638

Showing the first eight; more decompositions exist.
