Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632690, here are decompositions:

23 + 8632667 = 8632690
29 + 8632661 = 8632690
41 + 8632649 = 8632690
167 + 8632523 = 8632690
197 + 8632493 = 8632690
233 + 8632457 = 8632690
239 + 8632451 = 8632690
467 + 8632223 = 8632690

Showing the first eight; more decompositions exist.
