Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498044, here are decompositions:

5 + 31498039 = 31498044
37 + 31498007 = 31498044
41 + 31498003 = 31498044
47 + 31497997 = 31498044
103 + 31497941 = 31498044
113 + 31497931 = 31498044
173 + 31497871 = 31498044
181 + 31497863 = 31498044

Showing the first eight; more decompositions exist.
