Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705678, here are decompositions:

61 + 8705617 = 8705678
67 + 8705611 = 8705678
127 + 8705551 = 8705678
151 + 8705527 = 8705678
211 + 8705467 = 8705678
229 + 8705449 = 8705678
367 + 8705311 = 8705678
379 + 8705299 = 8705678

Showing the first eight; more decompositions exist.
