Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591808, here are decompositions:

37 + 8591771 = 8591808
61 + 8591747 = 8591808
97 + 8591711 = 8591808
191 + 8591617 = 8591808
307 + 8591501 = 8591808
359 + 8591449 = 8591808
367 + 8591441 = 8591808
389 + 8591419 = 8591808

Showing the first eight; more decompositions exist.
