Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619498, here are decompositions:

7 + 8619491 = 8619498
29 + 8619469 = 8619498
37 + 8619461 = 8619498
59 + 8619439 = 8619498
61 + 8619437 = 8619498
67 + 8619431 = 8619498
71 + 8619427 = 8619498
101 + 8619397 = 8619498

Showing the first eight; more decompositions exist.
