Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499194, here are decompositions:

5 + 31499189 = 31499194
11 + 31499183 = 31499194
131 + 31499063 = 31499194
137 + 31499057 = 31499194
173 + 31499021 = 31499194
191 + 31499003 = 31499194
227 + 31498967 = 31499194
263 + 31498931 = 31499194

Showing the first eight; more decompositions exist.
