Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619008, here are decompositions:

157 + 8618851 = 8619008
199 + 8618809 = 8619008
271 + 8618737 = 8619008
631 + 8618377 = 8619008
691 + 8618317 = 8619008
751 + 8618257 = 8619008
757 + 8618251 = 8619008
787 + 8618221 = 8619008

Showing the first eight; more decompositions exist.
