Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112638, here are decompositions:

17 + 112621 = 112638
37 + 112601 = 112638
61 + 112577 = 112638
67 + 112571 = 112638
79 + 112559 = 112638
131 + 112507 = 112638
137 + 112501 = 112638
157 + 112481 = 112638

Showing the first eight; more decompositions exist.
