Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651490, here are decompositions:

31 + 8651459 = 8651490
47 + 8651443 = 8651490
53 + 8651437 = 8651490
61 + 8651429 = 8651490
101 + 8651389 = 8651490
131 + 8651359 = 8651490
137 + 8651353 = 8651490
167 + 8651323 = 8651490

Showing the first eight; more decompositions exist.
