Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731026, here are decompositions:

43 + 8730983 = 8731026
79 + 8730947 = 8731026
97 + 8730929 = 8731026
107 + 8730919 = 8731026
113 + 8730913 = 8731026
137 + 8730889 = 8731026
163 + 8730863 = 8731026
167 + 8730859 = 8731026

Showing the first eight; more decompositions exist.
