Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642234, here are decompositions:

37 + 8642197 = 8642234
61 + 8642173 = 8642234
127 + 8642107 = 8642234
157 + 8642077 = 8642234
277 + 8641957 = 8642234
487 + 8641747 = 8642234
613 + 8641621 = 8642234
631 + 8641603 = 8642234

Showing the first eight; more decompositions exist.
