Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591984, here are decompositions:

43 + 8591941 = 8591984
97 + 8591887 = 8591984
157 + 8591827 = 8591984
211 + 8591773 = 8591984
367 + 8591617 = 8591984
397 + 8591587 = 8591984
421 + 8591563 = 8591984
607 + 8591377 = 8591984

Showing the first eight; more decompositions exist.
