Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591964, here are decompositions:

23 + 8591941 = 8591964
37 + 8591927 = 8591964
137 + 8591827 = 8591964
151 + 8591813 = 8591964
191 + 8591773 = 8591964
193 + 8591771 = 8591964
281 + 8591683 = 8591964
331 + 8591633 = 8591964

Showing the first eight; more decompositions exist.
