Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518046, here are decompositions:

23 + 31518023 = 31518046
47 + 31517999 = 31518046
83 + 31517963 = 31518046
137 + 31517909 = 31518046
167 + 31517879 = 31518046
317 + 31517729 = 31518046
347 + 31517699 = 31518046
449 + 31517597 = 31518046

Showing the first eight; more decompositions exist.
