Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731948, here are decompositions:

11 + 8731937 = 8731948
41 + 8731907 = 8731948
47 + 8731901 = 8731948
89 + 8731859 = 8731948
131 + 8731817 = 8731948
191 + 8731757 = 8731948
227 + 8731721 = 8731948
311 + 8731637 = 8731948

Showing the first eight; more decompositions exist.
