Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559576, here are decompositions:

3 + 31559573 = 31559576
109 + 31559467 = 31559576
163 + 31559413 = 31559576
193 + 31559383 = 31559576
313 + 31559263 = 31559576
337 + 31559239 = 31559576
613 + 31558963 = 31559576
619 + 31558957 = 31559576

Showing the first eight; more decompositions exist.
