Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497714, here are decompositions:

7 + 31497707 = 31497714
13 + 31497701 = 31497714
41 + 31497673 = 31497714
43 + 31497671 = 31497714
47 + 31497667 = 31497714
113 + 31497601 = 31497714
137 + 31497577 = 31497714
163 + 31497551 = 31497714

Showing the first eight; more decompositions exist.
