Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565024, here are decompositions:

97 + 31564927 = 31565024
103 + 31564921 = 31565024
151 + 31564873 = 31565024
193 + 31564831 = 31565024
367 + 31564657 = 31565024
433 + 31564591 = 31565024
523 + 31564501 = 31565024
577 + 31564447 = 31565024

Showing the first eight; more decompositions exist.
