Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711072, here are decompositions:

61 + 8711011 = 8711072
109 + 8710963 = 8711072
163 + 8710909 = 8711072
373 + 8710699 = 8711072
379 + 8710693 = 8711072
439 + 8710633 = 8711072
463 + 8710609 = 8711072
613 + 8710459 = 8711072

Showing the first eight; more decompositions exist.
