Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591936, here are decompositions:

37 + 8591899 = 8591936
109 + 8591827 = 8591936
127 + 8591809 = 8591936
163 + 8591773 = 8591936
313 + 8591623 = 8591936
337 + 8591599 = 8591936
349 + 8591587 = 8591936
373 + 8591563 = 8591936

Showing the first eight; more decompositions exist.
