Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499058, here are decompositions:

37 + 31499021 = 31499058
67 + 31498991 = 31499058
109 + 31498949 = 31499058
127 + 31498931 = 31499058
179 + 31498879 = 31499058
191 + 31498867 = 31499058
211 + 31498847 = 31499058
229 + 31498829 = 31499058

Showing the first eight; more decompositions exist.
