Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460286, here are decompositions:

5 + 31460281 = 31460286
7 + 31460279 = 31460286
19 + 31460267 = 31460286
23 + 31460263 = 31460286
89 + 31460197 = 31460286
113 + 31460173 = 31460286
149 + 31460137 = 31460286
157 + 31460129 = 31460286

Showing the first eight; more decompositions exist.
