Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678578, here are decompositions:

59 + 8678519 = 8678578
71 + 8678507 = 8678578
131 + 8678447 = 8678578
179 + 8678399 = 8678578
239 + 8678339 = 8678578
431 + 8678147 = 8678578
449 + 8678129 = 8678578
509 + 8678069 = 8678578

Showing the first eight; more decompositions exist.
