Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565592, here are decompositions:

31 + 31565561 = 31565592
53 + 31565539 = 31565592
101 + 31565491 = 31565592
131 + 31565461 = 31565592
181 + 31565411 = 31565592
193 + 31565399 = 31565592
239 + 31565353 = 31565592
241 + 31565351 = 31565592

Showing the first eight; more decompositions exist.
