Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637418, here are decompositions:

107 + 8637311 = 8637418
191 + 8637227 = 8637418
239 + 8637179 = 8637418
311 + 8637107 = 8637418
359 + 8637059 = 8637418
401 + 8637017 = 8637418
431 + 8636987 = 8637418
509 + 8636909 = 8637418

Showing the first eight; more decompositions exist.
