Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638674, here are decompositions:

13 + 8638661 = 8638674
41 + 8638633 = 8638674
47 + 8638627 = 8638674
53 + 8638621 = 8638674
131 + 8638543 = 8638674
157 + 8638517 = 8638674
193 + 8638481 = 8638674
197 + 8638477 = 8638674

Showing the first eight; more decompositions exist.
