Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599206, here are decompositions:

13 + 31599193 = 31599206
103 + 31599103 = 31599206
283 + 31598923 = 31599206
349 + 31598857 = 31599206
367 + 31598839 = 31599206
523 + 31598683 = 31599206
757 + 31598449 = 31599206
787 + 31598419 = 31599206

Showing the first eight; more decompositions exist.
