Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598816, here are decompositions:

37 + 31598779 = 31598816
367 + 31598449 = 31598816
397 + 31598419 = 31598816
439 + 31598377 = 31598816
463 + 31598353 = 31598816
577 + 31598239 = 31598816
673 + 31598143 = 31598816
787 + 31598029 = 31598816

Showing the first eight; more decompositions exist.
