Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565364, here are decompositions:

11 + 31565353 = 31565364
13 + 31565351 = 31565364
41 + 31565323 = 31565364
67 + 31565297 = 31565364
71 + 31565293 = 31565364
73 + 31565291 = 31565364
107 + 31565257 = 31565364
157 + 31565207 = 31565364

Showing the first eight; more decompositions exist.
