Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494958, here are decompositions:

71 + 31494887 = 31494958
149 + 31494809 = 31494958
191 + 31494767 = 31494958
251 + 31494707 = 31494958
269 + 31494689 = 31494958
347 + 31494611 = 31494958
449 + 31494509 = 31494958
461 + 31494497 = 31494958

Showing the first eight; more decompositions exist.
