Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463906, here are decompositions:

13 + 31463893 = 31463906
79 + 31463827 = 31463906
109 + 31463797 = 31463906
127 + 31463779 = 31463906
139 + 31463767 = 31463906
163 + 31463743 = 31463906
193 + 31463713 = 31463906
373 + 31463533 = 31463906

Showing the first eight; more decompositions exist.
