Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494612, here are decompositions:

29 + 31494583 = 31494612
31 + 31494581 = 31494612
59 + 31494553 = 31494612
103 + 31494509 = 31494612
109 + 31494503 = 31494612
173 + 31494439 = 31494612
181 + 31494431 = 31494612
211 + 31494401 = 31494612

Showing the first eight; more decompositions exist.
