Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637412, here are decompositions:

71 + 8637341 = 8637412
89 + 8637323 = 8637412
101 + 8637311 = 8637412
149 + 8637263 = 8637412
233 + 8637179 = 8637412
281 + 8637131 = 8637412
293 + 8637119 = 8637412
353 + 8637059 = 8637412

Showing the first eight; more decompositions exist.
