Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494982, here are decompositions:

3 + 31494979 = 31494982
59 + 31494923 = 31494982
173 + 31494809 = 31494982
269 + 31494713 = 31494982
293 + 31494689 = 31494982
401 + 31494581 = 31494982
479 + 31494503 = 31494982
503 + 31494479 = 31494982

Showing the first eight; more decompositions exist.
