Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498914, here are decompositions:

17 + 31498897 = 31498914
47 + 31498867 = 31498914
61 + 31498853 = 31498914
67 + 31498847 = 31498914
101 + 31498813 = 31498914
103 + 31498811 = 31498914
151 + 31498763 = 31498914
173 + 31498741 = 31498914

Showing the first eight; more decompositions exist.
