Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485622, here are decompositions:

11 + 31485611 = 31485622
23 + 31485599 = 31485622
89 + 31485533 = 31485622
149 + 31485473 = 31485622
173 + 31485449 = 31485622
191 + 31485431 = 31485622
239 + 31485383 = 31485622
263 + 31485359 = 31485622

Showing the first eight; more decompositions exist.
