Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711258, here are decompositions:

79 + 8711179 = 8711258
97 + 8711161 = 8711258
349 + 8710909 = 8711258
487 + 8710771 = 8711258
541 + 8710717 = 8711258
571 + 8710687 = 8711258
631 + 8710627 = 8711258
691 + 8710567 = 8711258

Showing the first eight; more decompositions exist.
