Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560590, here are decompositions:

3 + 31560587 = 31560590
7 + 31560583 = 31560590
31 + 31560559 = 31560590
67 + 31560523 = 31560590
157 + 31560433 = 31560590
199 + 31560391 = 31560590
283 + 31560307 = 31560590
571 + 31560019 = 31560590

Showing the first eight; more decompositions exist.
