Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643174, here are decompositions:

31 + 8643143 = 8643174
37 + 8643137 = 8643174
41 + 8643133 = 8643174
53 + 8643121 = 8643174
83 + 8643091 = 8643174
97 + 8643077 = 8643174
151 + 8643023 = 8643174
223 + 8642951 = 8643174

Showing the first eight; more decompositions exist.
