Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494856, here are decompositions:

47 + 31494809 = 31494856
89 + 31494767 = 31494856
149 + 31494707 = 31494856
167 + 31494689 = 31494856
347 + 31494509 = 31494856
353 + 31494503 = 31494856
359 + 31494497 = 31494856
389 + 31494467 = 31494856

Showing the first eight; more decompositions exist.
