Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734640, here are decompositions:

37 + 8734603 = 8734640
67 + 8734573 = 8734640
97 + 8734543 = 8734640
127 + 8734513 = 8734640
139 + 8734501 = 8734640
157 + 8734483 = 8734640
199 + 8734441 = 8734640
223 + 8734417 = 8734640

Showing the first eight; more decompositions exist.
