Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656974, here are decompositions:

41 + 8656933 = 8656974
71 + 8656903 = 8656974
83 + 8656891 = 8656974
103 + 8656871 = 8656974
127 + 8656847 = 8656974
167 + 8656807 = 8656974
173 + 8656801 = 8656974
241 + 8656733 = 8656974

Showing the first eight; more decompositions exist.
