Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565546, here are decompositions:

7 + 31565539 = 31565546
73 + 31565473 = 31565546
109 + 31565437 = 31565546
163 + 31565383 = 31565546
193 + 31565353 = 31565546
223 + 31565323 = 31565546
349 + 31565197 = 31565546
373 + 31565173 = 31565546

Showing the first eight; more decompositions exist.
