Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631626, here are decompositions:

109 + 8631517 = 8631626
127 + 8631499 = 8631626
307 + 8631319 = 8631626
349 + 8631277 = 8631626
379 + 8631247 = 8631626
397 + 8631229 = 8631626
433 + 8631193 = 8631626
643 + 8630983 = 8631626

Showing the first eight; more decompositions exist.
