Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498204, here are decompositions:

5 + 31498199 = 31498204
11 + 31498193 = 31498204
53 + 31498151 = 31498204
197 + 31498007 = 31498204
263 + 31497941 = 31498204
401 + 31497803 = 31498204
431 + 31497773 = 31498204
467 + 31497737 = 31498204

Showing the first eight; more decompositions exist.
