Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591996, here are decompositions:

97 + 8591899 = 8591996
109 + 8591887 = 8591996
223 + 8591773 = 8591996
307 + 8591689 = 8591996
313 + 8591683 = 8591996
373 + 8591623 = 8591996
379 + 8591617 = 8591996
397 + 8591599 = 8591996

Showing the first eight; more decompositions exist.
