Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637616, here are decompositions:

5 + 8637611 = 8637616
89 + 8637527 = 8637616
107 + 8637509 = 8637616
149 + 8637467 = 8637616
167 + 8637449 = 8637616
293 + 8637323 = 8637616
353 + 8637263 = 8637616
359 + 8637257 = 8637616

Showing the first eight; more decompositions exist.
