Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498854, here are decompositions:

5 + 31498849 = 31498854
7 + 31498847 = 31498854
17 + 31498837 = 31498854
41 + 31498813 = 31498854
43 + 31498811 = 31498854
113 + 31498741 = 31498854
151 + 31498703 = 31498854
197 + 31498657 = 31498854

Showing the first eight; more decompositions exist.
