Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498126, here are decompositions:

3 + 31498123 = 31498126
83 + 31498043 = 31498126
197 + 31497929 = 31498126
263 + 31497863 = 31498126
353 + 31497773 = 31498126
389 + 31497737 = 31498126
419 + 31497707 = 31498126
557 + 31497569 = 31498126

Showing the first eight; more decompositions exist.
