Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498056, here are decompositions:

13 + 31498043 = 31498056
17 + 31498039 = 31498056
47 + 31498009 = 31498056
53 + 31498003 = 31498056
59 + 31497997 = 31498056
127 + 31497929 = 31498056
173 + 31497883 = 31498056
193 + 31497863 = 31498056

Showing the first eight; more decompositions exist.
