Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494734, here are decompositions:

13 + 31494721 = 31494734
43 + 31494691 = 31494734
97 + 31494637 = 31494734
151 + 31494583 = 31494734
181 + 31494553 = 31494734
307 + 31494427 = 31494734
433 + 31494301 = 31494734
487 + 31494247 = 31494734

Showing the first eight; more decompositions exist.
