Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522014, here are decompositions:

23 + 31521991 = 31522014
37 + 31521977 = 31522014
61 + 31521953 = 31522014
127 + 31521887 = 31522014
131 + 31521883 = 31522014
151 + 31521863 = 31522014
163 + 31521851 = 31522014
331 + 31521683 = 31522014

Showing the first eight; more decompositions exist.
