Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498068, here are decompositions:

29 + 31498039 = 31498068
59 + 31498009 = 31498068
61 + 31498007 = 31498068
71 + 31497997 = 31498068
89 + 31497979 = 31498068
127 + 31497941 = 31498068
137 + 31497931 = 31498068
139 + 31497929 = 31498068

Showing the first eight; more decompositions exist.
