Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655564, here are decompositions:

37 + 8655527 = 8655564
67 + 8655497 = 8655564
107 + 8655457 = 8655564
131 + 8655433 = 8655564
163 + 8655401 = 8655564
193 + 8655371 = 8655564
233 + 8655331 = 8655564
251 + 8655313 = 8655564

Showing the first eight; more decompositions exist.
