Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623930, here are decompositions:

47 + 8623883 = 8623930
83 + 8623847 = 8623930
131 + 8623799 = 8623930
137 + 8623793 = 8623930
167 + 8623763 = 8623930
173 + 8623757 = 8623930
179 + 8623751 = 8623930
251 + 8623679 = 8623930

Showing the first eight; more decompositions exist.
