Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700688, here are decompositions:

89 + 8700599 = 8700688
107 + 8700581 = 8700688
149 + 8700539 = 8700688
167 + 8700521 = 8700688
239 + 8700449 = 8700688
257 + 8700431 = 8700688
281 + 8700407 = 8700688
389 + 8700299 = 8700688

Showing the first eight; more decompositions exist.
