Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642264, here are decompositions:

67 + 8642197 = 8642264
157 + 8642107 = 8642264
277 + 8641987 = 8642264
307 + 8641957 = 8642264
373 + 8641891 = 8642264
457 + 8641807 = 8642264
523 + 8641741 = 8642264
613 + 8641651 = 8642264

Showing the first eight; more decompositions exist.
