Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673856, here are decompositions:

17 + 8673839 = 8673856
173 + 8673683 = 8673856
179 + 8673677 = 8673856
263 + 8673593 = 8673856
467 + 8673389 = 8673856
479 + 8673377 = 8673856
509 + 8673347 = 8673856
563 + 8673293 = 8673856

Showing the first eight; more decompositions exist.
