Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598564, here are decompositions:

43 + 31598521 = 31598564
163 + 31598401 = 31598564
211 + 31598353 = 31598564
337 + 31598227 = 31598564
373 + 31598191 = 31598564
421 + 31598143 = 31598564
463 + 31598101 = 31598564
577 + 31597987 = 31598564

Showing the first eight; more decompositions exist.
