Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565604, here are decompositions:

43 + 31565561 = 31565604
107 + 31565497 = 31565604
113 + 31565491 = 31565604
131 + 31565473 = 31565604
167 + 31565437 = 31565604
173 + 31565431 = 31565604
181 + 31565423 = 31565604
193 + 31565411 = 31565604

Showing the first eight; more decompositions exist.
