Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619492, here are decompositions:

19 + 8619473 = 8619492
23 + 8619469 = 8619492
31 + 8619461 = 8619492
53 + 8619439 = 8619492
59 + 8619433 = 8619492
61 + 8619431 = 8619492
71 + 8619421 = 8619492
139 + 8619353 = 8619492

Showing the first eight; more decompositions exist.
