Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498338, here are decompositions:

31 + 31498307 = 31498338
59 + 31498279 = 31498338
61 + 31498277 = 31498338
139 + 31498199 = 31498338
149 + 31498189 = 31498338
227 + 31498111 = 31498338
251 + 31498087 = 31498338
269 + 31498069 = 31498338

Showing the first eight; more decompositions exist.
