Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687906, here are decompositions:

79 + 8687827 = 8687906
109 + 8687797 = 8687906
193 + 8687713 = 8687906
307 + 8687599 = 8687906
439 + 8687467 = 8687906
523 + 8687383 = 8687906
547 + 8687359 = 8687906
607 + 8687299 = 8687906

Showing the first eight; more decompositions exist.
