Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647490, here are decompositions:

31 + 8647459 = 8647490
43 + 8647447 = 8647490
73 + 8647417 = 8647490
79 + 8647411 = 8647490
97 + 8647393 = 8647490
307 + 8647183 = 8647490
367 + 8647123 = 8647490
463 + 8647027 = 8647490

Showing the first eight; more decompositions exist.
