Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565662, here are decompositions:

59 + 31565603 = 31565662
101 + 31565561 = 31565662
239 + 31565423 = 31565662
251 + 31565411 = 31565662
263 + 31565399 = 31565662
311 + 31565351 = 31565662
353 + 31565309 = 31565662
383 + 31565279 = 31565662

Showing the first eight; more decompositions exist.
