Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498038, here are decompositions:

29 + 31498009 = 31498038
31 + 31498007 = 31498038
41 + 31497997 = 31498038
59 + 31497979 = 31498038
97 + 31497941 = 31498038
107 + 31497931 = 31498038
109 + 31497929 = 31498038
167 + 31497871 = 31498038

Showing the first eight; more decompositions exist.
