Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620078, here are decompositions:

29 + 8620049 = 8620078
281 + 8619797 = 8620078
359 + 8619719 = 8620078
491 + 8619587 = 8620078
569 + 8619509 = 8620078
587 + 8619491 = 8620078
617 + 8619461 = 8620078
641 + 8619437 = 8620078

Showing the first eight; more decompositions exist.
