Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565350, here are decompositions:

41 + 31565309 = 31565350
53 + 31565297 = 31565350
59 + 31565291 = 31565350
71 + 31565279 = 31565350
101 + 31565249 = 31565350
191 + 31565159 = 31565350
233 + 31565117 = 31565350
263 + 31565087 = 31565350

Showing the first eight; more decompositions exist.
