Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639744, here are decompositions:

31 + 8639713 = 8639744
97 + 8639647 = 8639744
181 + 8639563 = 8639744
193 + 8639551 = 8639744
283 + 8639461 = 8639744
331 + 8639413 = 8639744
397 + 8639347 = 8639744
601 + 8639143 = 8639744

Showing the first eight; more decompositions exist.
