Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599758, here are decompositions:

31 + 31599727 = 31599758
109 + 31599649 = 31599758
271 + 31599487 = 31599758
409 + 31599349 = 31599758
499 + 31599259 = 31599758
601 + 31599157 = 31599758
769 + 31598989 = 31599758
811 + 31598947 = 31599758

Showing the first eight; more decompositions exist.
