Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719130, here are decompositions:

3 + 8719127 = 8719130
31 + 8719099 = 8719130
73 + 8719057 = 8719130
109 + 8719021 = 8719130
127 + 8719003 = 8719130
157 + 8718973 = 8719130
181 + 8718949 = 8719130
223 + 8718907 = 8719130

Showing the first eight; more decompositions exist.
