Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494014, here are decompositions:

31 + 31493983 = 31494014
73 + 31493941 = 31494014
157 + 31493857 = 31494014
163 + 31493851 = 31494014
193 + 31493821 = 31494014
271 + 31493743 = 31494014
337 + 31493677 = 31494014
373 + 31493641 = 31494014

Showing the first eight; more decompositions exist.
