Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458564, here are decompositions:

23 + 31458541 = 31458564
37 + 31458527 = 31458564
83 + 31458481 = 31458564
113 + 31458451 = 31458564
127 + 31458437 = 31458564
191 + 31458373 = 31458564
233 + 31458331 = 31458564
367 + 31458197 = 31458564

Showing the first eight; more decompositions exist.
