Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565944, here are decompositions:

173 + 31565771 = 31565944
251 + 31565693 = 31565944
281 + 31565663 = 31565944
383 + 31565561 = 31565944
521 + 31565423 = 31565944
593 + 31565351 = 31565944
647 + 31565297 = 31565944
653 + 31565291 = 31565944

Showing the first eight; more decompositions exist.
