Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492204, here are decompositions:

41 + 31492163 = 31492204
47 + 31492157 = 31492204
113 + 31492091 = 31492204
131 + 31492073 = 31492204
137 + 31492067 = 31492204
173 + 31492031 = 31492204
311 + 31491893 = 31492204
467 + 31491737 = 31492204

Showing the first eight; more decompositions exist.
