Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527670, here are decompositions:

11 + 31527659 = 31527670
101 + 31527569 = 31527670
137 + 31527533 = 31527670
149 + 31527521 = 31527670
173 + 31527497 = 31527670
179 + 31527491 = 31527670
257 + 31527413 = 31527670
263 + 31527407 = 31527670

Showing the first eight; more decompositions exist.
