Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498002, here are decompositions:

5 + 31497997 = 31498002
23 + 31497979 = 31498002
61 + 31497941 = 31498002
71 + 31497931 = 31498002
73 + 31497929 = 31498002
131 + 31497871 = 31498002
139 + 31497863 = 31498002
199 + 31497803 = 31498002

Showing the first eight; more decompositions exist.
