Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564734, here are decompositions:

11 + 31564723 = 31564734
13 + 31564721 = 31564734
73 + 31564661 = 31564734
233 + 31564501 = 31564734
347 + 31564387 = 31564734
373 + 31564361 = 31564734
401 + 31564333 = 31564734
463 + 31564271 = 31564734

Showing the first eight; more decompositions exist.
