Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468672, here are decompositions:

5 + 31468667 = 31468672
41 + 31468631 = 31468672
83 + 31468589 = 31468672
101 + 31468571 = 31468672
113 + 31468559 = 31468672
149 + 31468523 = 31468672
173 + 31468499 = 31468672
269 + 31468403 = 31468672

Showing the first eight; more decompositions exist.
