Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659142, here are decompositions:

43 + 8659099 = 8659142
181 + 8658961 = 8659142
199 + 8658943 = 8659142
211 + 8658931 = 8659142
223 + 8658919 = 8659142
313 + 8658829 = 8659142
433 + 8658709 = 8659142
463 + 8658679 = 8659142

Showing the first eight; more decompositions exist.
