Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565602, here are decompositions:

41 + 31565561 = 31565602
179 + 31565423 = 31565602
191 + 31565411 = 31565602
251 + 31565351 = 31565602
293 + 31565309 = 31565602
311 + 31565291 = 31565602
353 + 31565249 = 31565602
443 + 31565159 = 31565602

Showing the first eight; more decompositions exist.
