Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598726, here are decompositions:

43 + 31598683 = 31598726
79 + 31598647 = 31598726
277 + 31598449 = 31598726
307 + 31598419 = 31598726
349 + 31598377 = 31598726
373 + 31598353 = 31598726
487 + 31598239 = 31598726
499 + 31598227 = 31598726

Showing the first eight; more decompositions exist.
