Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599298, here are decompositions:

197 + 31599101 = 31599298
239 + 31599059 = 31599298
359 + 31598939 = 31599298
389 + 31598909 = 31599298
431 + 31598867 = 31599298
509 + 31598789 = 31599298
761 + 31598537 = 31599298
839 + 31598459 = 31599298

Showing the first eight; more decompositions exist.
