Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564754, here are decompositions:

31 + 31564723 = 31564754
97 + 31564657 = 31564754
163 + 31564591 = 31564754
223 + 31564531 = 31564754
307 + 31564447 = 31564754
367 + 31564387 = 31564754
421 + 31564333 = 31564754
433 + 31564321 = 31564754

Showing the first eight; more decompositions exist.
