Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498362, here are decompositions:

13 + 31498349 = 31498362
19 + 31498343 = 31498362
73 + 31498289 = 31498362
83 + 31498279 = 31498362
89 + 31498273 = 31498362
109 + 31498253 = 31498362
149 + 31498213 = 31498362
163 + 31498199 = 31498362

Showing the first eight; more decompositions exist.
