Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497114, here are decompositions:

31 + 31497083 = 31497114
43 + 31497071 = 31497114
107 + 31497007 = 31497114
113 + 31497001 = 31497114
137 + 31496977 = 31497114
151 + 31496963 = 31497114
157 + 31496957 = 31497114
167 + 31496947 = 31497114

Showing the first eight; more decompositions exist.
