Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623942, here are decompositions:

3 + 8623939 = 8623942
59 + 8623883 = 8623942
149 + 8623793 = 8623942
179 + 8623763 = 8623942
191 + 8623751 = 8623942
263 + 8623679 = 8623942
281 + 8623661 = 8623942
359 + 8623583 = 8623942

Showing the first eight; more decompositions exist.
