Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617512, here are decompositions:

73 + 8617439 = 8617512
131 + 8617381 = 8617512
139 + 8617373 = 8617512
151 + 8617361 = 8617512
179 + 8617333 = 8617512
193 + 8617319 = 8617512
199 + 8617313 = 8617512
251 + 8617261 = 8617512

Showing the first eight; more decompositions exist.
