Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731150, here are decompositions:

11 + 8731139 = 8731150
41 + 8731109 = 8731150
47 + 8731103 = 8731150
53 + 8731097 = 8731150
167 + 8730983 = 8731150
173 + 8730977 = 8731150
257 + 8730893 = 8731150
269 + 8730881 = 8731150

Showing the first eight; more decompositions exist.
