Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498316, here are decompositions:

37 + 31498279 = 31498316
43 + 31498273 = 31498316
103 + 31498213 = 31498316
127 + 31498189 = 31498316
193 + 31498123 = 31498316
229 + 31498087 = 31498316
277 + 31498039 = 31498316
307 + 31498009 = 31498316

Showing the first eight; more decompositions exist.
