Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622172, here are decompositions:

59 + 8622113 = 8622172
101 + 8622071 = 8622172
131 + 8622041 = 8622172
149 + 8622023 = 8622172
233 + 8621939 = 8622172
239 + 8621933 = 8622172
311 + 8621861 = 8622172
353 + 8621819 = 8622172

Showing the first eight; more decompositions exist.
