Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654520, here are decompositions:

31 + 8654489 = 8654520
37 + 8654483 = 8654520
53 + 8654467 = 8654520
59 + 8654461 = 8654520
67 + 8654453 = 8654520
73 + 8654447 = 8654520
89 + 8654431 = 8654520
131 + 8654389 = 8654520

Showing the first eight; more decompositions exist.
