Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645936, here are decompositions:

37 + 8645899 = 8645936
73 + 8645863 = 8645936
163 + 8645773 = 8645936
283 + 8645653 = 8645936
349 + 8645587 = 8645936
487 + 8645449 = 8645936
577 + 8645359 = 8645936
643 + 8645293 = 8645936

Showing the first eight; more decompositions exist.
