Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499226, here are decompositions:

37 + 31499189 = 31499226
43 + 31499183 = 31499226
67 + 31499159 = 31499226
89 + 31499137 = 31499226
149 + 31499077 = 31499226
163 + 31499063 = 31499226
193 + 31499033 = 31499226
223 + 31499003 = 31499226

Showing the first eight; more decompositions exist.
