Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527586, here are decompositions:

3 + 31527583 = 31527586
17 + 31527569 = 31527586
53 + 31527533 = 31527586
89 + 31527497 = 31527586
173 + 31527413 = 31527586
179 + 31527407 = 31527586
197 + 31527389 = 31527586
263 + 31527323 = 31527586

Showing the first eight; more decompositions exist.
