Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470850, here are decompositions:

3 + 31470847 = 31470850
17 + 31470833 = 31470850
23 + 31470827 = 31470850
149 + 31470701 = 31470850
197 + 31470653 = 31470850
227 + 31470623 = 31470850
269 + 31470581 = 31470850
293 + 31470557 = 31470850

Showing the first eight; more decompositions exist.
