Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641936, here are decompositions:

53 + 8641883 = 8641936
227 + 8641709 = 8641936
239 + 8641697 = 8641936
263 + 8641673 = 8641936
293 + 8641643 = 8641936
389 + 8641547 = 8641936
419 + 8641517 = 8641936
467 + 8641469 = 8641936

Showing the first eight; more decompositions exist.
