Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498860, here are decompositions:

7 + 31498853 = 31498860
11 + 31498849 = 31498860
13 + 31498847 = 31498860
23 + 31498837 = 31498860
31 + 31498829 = 31498860
47 + 31498813 = 31498860
97 + 31498763 = 31498860
157 + 31498703 = 31498860

Showing the first eight; more decompositions exist.
