Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518934, here are decompositions:

11 + 31518923 = 31518934
53 + 31518881 = 31518934
71 + 31518863 = 31518934
107 + 31518827 = 31518934
257 + 31518677 = 31518934
281 + 31518653 = 31518934
443 + 31518491 = 31518934
467 + 31518467 = 31518934

Showing the first eight; more decompositions exist.
