Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498352, here are decompositions:

3 + 31498349 = 31498352
73 + 31498279 = 31498352
79 + 31498273 = 31498352
139 + 31498213 = 31498352
163 + 31498189 = 31498352
229 + 31498123 = 31498352
241 + 31498111 = 31498352
283 + 31498069 = 31498352

Showing the first eight; more decompositions exist.
