Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494934, here are decompositions:

11 + 31494923 = 31494934
47 + 31494887 = 31494934
167 + 31494767 = 31494934
197 + 31494737 = 31494934
227 + 31494707 = 31494934
353 + 31494581 = 31494934
431 + 31494503 = 31494934
467 + 31494467 = 31494934

Showing the first eight; more decompositions exist.
