Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742732, here are decompositions:

43 + 8742689 = 8742732
59 + 8742673 = 8742732
79 + 8742653 = 8742732
109 + 8742623 = 8742732
181 + 8742551 = 8742732
191 + 8742541 = 8742732
233 + 8742499 = 8742732
239 + 8742493 = 8742732

Showing the first eight; more decompositions exist.
