Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598894, here are decompositions:

7 + 31598887 = 31598894
31 + 31598863 = 31598894
37 + 31598857 = 31598894
193 + 31598701 = 31598894
211 + 31598683 = 31598894
373 + 31598521 = 31598894
541 + 31598353 = 31598894
751 + 31598143 = 31598894

Showing the first eight; more decompositions exist.
