Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654490, here are decompositions:

7 + 8654483 = 8654490
23 + 8654467 = 8654490
29 + 8654461 = 8654490
37 + 8654453 = 8654490
43 + 8654447 = 8654490
59 + 8654431 = 8654490
101 + 8654389 = 8654490
109 + 8654381 = 8654490

Showing the first eight; more decompositions exist.
