Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619580, here are decompositions:

29 + 8619551 = 8619580
41 + 8619539 = 8619580
71 + 8619509 = 8619580
89 + 8619491 = 8619580
107 + 8619473 = 8619580
149 + 8619431 = 8619580
227 + 8619353 = 8619580
311 + 8619269 = 8619580

Showing the first eight; more decompositions exist.
