Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565414, here are decompositions:

3 + 31565411 = 31565414
31 + 31565383 = 31565414
37 + 31565377 = 31565414
61 + 31565353 = 31565414
157 + 31565257 = 31565414
193 + 31565221 = 31565414
241 + 31565173 = 31565414
313 + 31565101 = 31565414

Showing the first eight; more decompositions exist.
