Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641732, here are decompositions:

23 + 8641709 = 8641732
59 + 8641673 = 8641732
89 + 8641643 = 8641732
101 + 8641631 = 8641732
191 + 8641541 = 8641732
263 + 8641469 = 8641732
311 + 8641421 = 8641732
383 + 8641349 = 8641732

Showing the first eight; more decompositions exist.
