Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565674, here are decompositions:

3 + 31565671 = 31565674
11 + 31565663 = 31565674
71 + 31565603 = 31565674
113 + 31565561 = 31565674
251 + 31565423 = 31565674
263 + 31565411 = 31565674
383 + 31565291 = 31565674
443 + 31565231 = 31565674

Showing the first eight; more decompositions exist.
