Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499404, here are decompositions:

3 + 31499401 = 31499404
5 + 31499399 = 31499404
17 + 31499387 = 31499404
107 + 31499297 = 31499404
113 + 31499291 = 31499404
137 + 31499267 = 31499404
173 + 31499231 = 31499404
347 + 31499057 = 31499404

Showing the first eight; more decompositions exist.
