Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498010, here are decompositions:

3 + 31498007 = 31498010
7 + 31498003 = 31498010
13 + 31497997 = 31498010
31 + 31497979 = 31498010
79 + 31497931 = 31498010
127 + 31497883 = 31498010
139 + 31497871 = 31498010
151 + 31497859 = 31498010

Showing the first eight; more decompositions exist.
