Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463772, here are decompositions:

5 + 31463767 = 31463772
13 + 31463759 = 31463772
29 + 31463743 = 31463772
59 + 31463713 = 31463772
83 + 31463689 = 31463772
181 + 31463591 = 31463772
239 + 31463533 = 31463772
283 + 31463489 = 31463772

Showing the first eight; more decompositions exist.
