Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719678, here are decompositions:

17 + 8719661 = 8719678
101 + 8719577 = 8719678
137 + 8719541 = 8719678
257 + 8719421 = 8719678
311 + 8719367 = 8719678
389 + 8719289 = 8719678
467 + 8719211 = 8719678
479 + 8719199 = 8719678

Showing the first eight; more decompositions exist.
