Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498974, here are decompositions:

7 + 31498967 = 31498974
11 + 31498963 = 31498974
43 + 31498931 = 31498974
61 + 31498913 = 31498974
107 + 31498867 = 31498974
127 + 31498847 = 31498974
137 + 31498837 = 31498974
163 + 31498811 = 31498974

Showing the first eight; more decompositions exist.
