Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639696, here are decompositions:

97 + 8639599 = 8639696
157 + 8639539 = 8639696
283 + 8639413 = 8639696
349 + 8639347 = 8639696
397 + 8639299 = 8639696
433 + 8639263 = 8639696
547 + 8639149 = 8639696
577 + 8639119 = 8639696

Showing the first eight; more decompositions exist.
