Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498058, here are decompositions:

19 + 31498039 = 31498058
61 + 31497997 = 31498058
79 + 31497979 = 31498058
127 + 31497931 = 31498058
199 + 31497859 = 31498058
307 + 31497751 = 31498058
331 + 31497727 = 31498058
337 + 31497721 = 31498058

Showing the first eight; more decompositions exist.
