Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620018, here are decompositions:

149 + 8619869 = 8620018
227 + 8619791 = 8620018
431 + 8619587 = 8620018
467 + 8619551 = 8620018
479 + 8619539 = 8620018
509 + 8619509 = 8620018
557 + 8619461 = 8620018
587 + 8619431 = 8620018

Showing the first eight; more decompositions exist.
