Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534644, here are decompositions:

7 + 31534637 = 31534644
13 + 31534631 = 31534644
47 + 31534597 = 31534644
83 + 31534561 = 31534644
101 + 31534543 = 31534644
151 + 31534493 = 31534644
157 + 31534487 = 31534644
233 + 31534411 = 31534644

Showing the first eight; more decompositions exist.
