Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564084, here are decompositions:

5 + 31564079 = 31564084
131 + 31563953 = 31564084
137 + 31563947 = 31564084
173 + 31563911 = 31564084
257 + 31563827 = 31564084
311 + 31563773 = 31564084
347 + 31563737 = 31564084
401 + 31563683 = 31564084

Showing the first eight; more decompositions exist.
