Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498410, here are decompositions:

43 + 31498367 = 31498410
61 + 31498349 = 31498410
67 + 31498343 = 31498410
103 + 31498307 = 31498410
131 + 31498279 = 31498410
137 + 31498273 = 31498410
157 + 31498253 = 31498410
193 + 31498217 = 31498410

Showing the first eight; more decompositions exist.
