Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731086, here are decompositions:

17 + 8731069 = 8731086
47 + 8731039 = 8731086
59 + 8731027 = 8731086
103 + 8730983 = 8731086
109 + 8730977 = 8731086
137 + 8730949 = 8731086
139 + 8730947 = 8731086
157 + 8730929 = 8731086

Showing the first eight; more decompositions exist.
