Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637464, here are decompositions:

13 + 8637451 = 8637464
37 + 8637427 = 8637464
127 + 8637337 = 8637464
163 + 8637301 = 8637464
211 + 8637253 = 8637464
313 + 8637151 = 8637464
331 + 8637133 = 8637464
373 + 8637091 = 8637464

Showing the first eight; more decompositions exist.
