Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637178, here are decompositions:

47 + 8637131 = 8637178
59 + 8637119 = 8637178
71 + 8637107 = 8637178
191 + 8636987 = 8637178
257 + 8636921 = 8637178
269 + 8636909 = 8637178
359 + 8636819 = 8637178
419 + 8636759 = 8637178

Showing the first eight; more decompositions exist.
