Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731960, here are decompositions:

23 + 8731937 = 8731960
47 + 8731913 = 8731960
53 + 8731907 = 8731960
59 + 8731901 = 8731960
101 + 8731859 = 8731960
173 + 8731787 = 8731960
197 + 8731763 = 8731960
239 + 8731721 = 8731960

Showing the first eight; more decompositions exist.
