Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498994, here are decompositions:

3 + 31498991 = 31498994
31 + 31498963 = 31498994
97 + 31498897 = 31498994
127 + 31498867 = 31498994
157 + 31498837 = 31498994
181 + 31498813 = 31498994
337 + 31498657 = 31498994
523 + 31498471 = 31498994

Showing the first eight; more decompositions exist.
