Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591864, here are decompositions:

37 + 8591827 = 8591864
181 + 8591683 = 8591864
241 + 8591623 = 8591864
271 + 8591593 = 8591864
277 + 8591587 = 8591864
331 + 8591533 = 8591864
397 + 8591467 = 8591864
433 + 8591431 = 8591864

Showing the first eight; more decompositions exist.
