Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642732, here are decompositions:

151 + 8642581 = 8642732
199 + 8642533 = 8642732
223 + 8642509 = 8642732
283 + 8642449 = 8642732
349 + 8642383 = 8642732
613 + 8642119 = 8642732
673 + 8642059 = 8642732
823 + 8641909 = 8642732

Showing the first eight; more decompositions exist.
