Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598690, here are decompositions:

3 + 31598687 = 31598690
7 + 31598683 = 31598690
43 + 31598647 = 31598690
241 + 31598449 = 31598690
271 + 31598419 = 31598690
313 + 31598377 = 31598690
337 + 31598353 = 31598690
463 + 31598227 = 31598690

Showing the first eight; more decompositions exist.
