Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626172, here are decompositions:

3 + 8626169 = 8626172
13 + 8626159 = 8626172
31 + 8626141 = 8626172
43 + 8626129 = 8626172
73 + 8626099 = 8626172
109 + 8626063 = 8626172
193 + 8625979 = 8626172
199 + 8625973 = 8626172

Showing the first eight; more decompositions exist.
