Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637584, here are decompositions:

61 + 8637523 = 8637584
103 + 8637481 = 8637584
157 + 8637427 = 8637584
211 + 8637373 = 8637584
283 + 8637301 = 8637584
331 + 8637253 = 8637584
337 + 8637247 = 8637584
421 + 8637163 = 8637584

Showing the first eight; more decompositions exist.
