Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642174, here are decompositions:

67 + 8642107 = 8642174
97 + 8642077 = 8642174
283 + 8641891 = 8642174
367 + 8641807 = 8642174
433 + 8641741 = 8642174
523 + 8641651 = 8642174
571 + 8641603 = 8642174
631 + 8641543 = 8642174

Showing the first eight; more decompositions exist.
