Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629172, here are decompositions:

3 + 8629169 = 8629172
31 + 8629141 = 8629172
109 + 8629063 = 8629172
163 + 8629009 = 8629172
199 + 8628973 = 8629172
283 + 8628889 = 8629172
313 + 8628859 = 8629172
373 + 8628799 = 8629172

Showing the first eight; more decompositions exist.
