Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463936, here are decompositions:

43 + 31463893 = 31463936
79 + 31463857 = 31463936
109 + 31463827 = 31463936
139 + 31463797 = 31463936
157 + 31463779 = 31463936
193 + 31463743 = 31463936
223 + 31463713 = 31463936
349 + 31463587 = 31463936

Showing the first eight; more decompositions exist.
