Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591744, here are decompositions:

61 + 8591683 = 8591744
127 + 8591617 = 8591744
151 + 8591593 = 8591744
157 + 8591587 = 8591744
181 + 8591563 = 8591744
211 + 8591533 = 8591744
277 + 8591467 = 8591744
313 + 8591431 = 8591744

Showing the first eight; more decompositions exist.
