Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637154, here are decompositions:

3 + 8637151 = 8637154
23 + 8637131 = 8637154
47 + 8637107 = 8637154
101 + 8637053 = 8637154
137 + 8637017 = 8637154
167 + 8636987 = 8637154
233 + 8636921 = 8637154
353 + 8636801 = 8637154

Showing the first eight; more decompositions exist.
