Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498332, here are decompositions:

43 + 31498289 = 31498332
53 + 31498279 = 31498332
59 + 31498273 = 31498332
79 + 31498253 = 31498332
139 + 31498193 = 31498332
181 + 31498151 = 31498332
263 + 31498069 = 31498332
293 + 31498039 = 31498332

Showing the first eight; more decompositions exist.
