Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632720, here are decompositions:

3 + 8632717 = 8632720
53 + 8632667 = 8632720
59 + 8632661 = 8632720
71 + 8632649 = 8632720
191 + 8632529 = 8632720
197 + 8632523 = 8632720
227 + 8632493 = 8632720
233 + 8632487 = 8632720

Showing the first eight; more decompositions exist.
