Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700778, here are decompositions:

5 + 8700773 = 8700778
11 + 8700767 = 8700778
179 + 8700599 = 8700778
197 + 8700581 = 8700778
239 + 8700539 = 8700778
257 + 8700521 = 8700778
311 + 8700467 = 8700778
347 + 8700431 = 8700778

Showing the first eight; more decompositions exist.
