Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731146, here are decompositions:

5 + 8731141 = 8731146
7 + 8731139 = 8731146
37 + 8731109 = 8731146
43 + 8731103 = 8731146
107 + 8731039 = 8731146
163 + 8730983 = 8731146
197 + 8730949 = 8731146
199 + 8730947 = 8731146

Showing the first eight; more decompositions exist.
