Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669942, here are decompositions:

3 + 8669939 = 8669942
13 + 8669929 = 8669942
19 + 8669923 = 8669942
31 + 8669911 = 8669942
241 + 8669701 = 8669942
271 + 8669671 = 8669942
313 + 8669629 = 8669942
331 + 8669611 = 8669942

Showing the first eight; more decompositions exist.
