Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642108, here are decompositions:

31 + 8642077 = 8642108
151 + 8641957 = 8642108
199 + 8641909 = 8642108
367 + 8641741 = 8642108
439 + 8641669 = 8642108
457 + 8641651 = 8642108
487 + 8641621 = 8642108
757 + 8641351 = 8642108

Showing the first eight; more decompositions exist.
