Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498202, here are decompositions:

3 + 31498199 = 31498202
13 + 31498189 = 31498202
79 + 31498123 = 31498202
163 + 31498039 = 31498202
193 + 31498009 = 31498202
199 + 31498003 = 31498202
223 + 31497979 = 31498202
271 + 31497931 = 31498202

Showing the first eight; more decompositions exist.
