Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598760, here are decompositions:

7 + 31598753 = 31598760
43 + 31598717 = 31598760
59 + 31598701 = 31598760
73 + 31598687 = 31598760
113 + 31598647 = 31598760
223 + 31598537 = 31598760
239 + 31598521 = 31598760
241 + 31598519 = 31598760

Showing the first eight; more decompositions exist.
