Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494814, here are decompositions:

5 + 31494809 = 31494814
47 + 31494767 = 31494814
101 + 31494713 = 31494814
107 + 31494707 = 31494814
233 + 31494581 = 31494814
311 + 31494503 = 31494814
317 + 31494497 = 31494814
347 + 31494467 = 31494814

Showing the first eight; more decompositions exist.
