Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498426, here are decompositions:

5 + 31498421 = 31498426
59 + 31498367 = 31498426
83 + 31498343 = 31498426
137 + 31498289 = 31498426
149 + 31498277 = 31498426
173 + 31498253 = 31498426
227 + 31498199 = 31498426
233 + 31498193 = 31498426

Showing the first eight; more decompositions exist.
