Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731912, here are decompositions:

5 + 8731907 = 8731912
11 + 8731901 = 8731912
53 + 8731859 = 8731912
149 + 8731763 = 8731912
191 + 8731721 = 8731912
239 + 8731673 = 8731912
251 + 8731661 = 8731912
269 + 8731643 = 8731912

Showing the first eight; more decompositions exist.
