Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494702, here are decompositions:

11 + 31494691 = 31494702
13 + 31494689 = 31494702
23 + 31494679 = 31494702
59 + 31494643 = 31494702
149 + 31494553 = 31494702
193 + 31494509 = 31494702
199 + 31494503 = 31494702
223 + 31494479 = 31494702

Showing the first eight; more decompositions exist.
