Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498396, here are decompositions:

29 + 31498367 = 31498396
47 + 31498349 = 31498396
53 + 31498343 = 31498396
89 + 31498307 = 31498396
107 + 31498289 = 31498396
179 + 31498217 = 31498396
197 + 31498199 = 31498396
353 + 31498043 = 31498396

Showing the first eight; more decompositions exist.
