Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712678, here are decompositions:

17 + 8712661 = 8712678
67 + 8712611 = 8712678
101 + 8712577 = 8712678
131 + 8712547 = 8712678
181 + 8712497 = 8712678
257 + 8712421 = 8712678
281 + 8712397 = 8712678
307 + 8712371 = 8712678

Showing the first eight; more decompositions exist.
