Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598744, here are decompositions:

43 + 31598701 = 31598744
61 + 31598683 = 31598744
97 + 31598647 = 31598744
223 + 31598521 = 31598744
367 + 31598377 = 31598744
601 + 31598143 = 31598744
607 + 31598137 = 31598744
643 + 31598101 = 31598744

Showing the first eight; more decompositions exist.
