Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731938, here are decompositions:

31 + 8731907 = 8731938
37 + 8731901 = 8731938
71 + 8731867 = 8731938
79 + 8731859 = 8731938
107 + 8731831 = 8731938
151 + 8731787 = 8731938
181 + 8731757 = 8731938
227 + 8731711 = 8731938

Showing the first eight; more decompositions exist.
