Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565710, here are decompositions:

17 + 31565693 = 31565710
47 + 31565663 = 31565710
107 + 31565603 = 31565710
149 + 31565561 = 31565710
311 + 31565399 = 31565710
359 + 31565351 = 31565710
401 + 31565309 = 31565710
419 + 31565291 = 31565710

Showing the first eight; more decompositions exist.
