Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943638, here are decompositions:

37 + 943601 = 943638
67 + 943571 = 943638
71 + 943567 = 943638
97 + 943541 = 943638
127 + 943511 = 943638
139 + 943499 = 943638
167 + 943471 = 943638
229 + 943409 = 943638

Showing the first eight; more decompositions exist.
