Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637480, here are decompositions:

13 + 8637467 = 8637480
29 + 8637451 = 8637480
31 + 8637449 = 8637480
53 + 8637427 = 8637480
101 + 8637379 = 8637480
107 + 8637373 = 8637480
139 + 8637341 = 8637480
157 + 8637323 = 8637480

Showing the first eight; more decompositions exist.
