Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731930, here are decompositions:

17 + 8731913 = 8731930
23 + 8731907 = 8731930
29 + 8731901 = 8731930
71 + 8731859 = 8731930
113 + 8731817 = 8731930
167 + 8731763 = 8731930
173 + 8731757 = 8731930
257 + 8731673 = 8731930

Showing the first eight; more decompositions exist.
