Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599562, here are decompositions:

11 + 31599551 = 31599562
131 + 31599431 = 31599562
173 + 31599389 = 31599562
389 + 31599173 = 31599562
461 + 31599101 = 31599562
503 + 31599059 = 31599562
653 + 31598909 = 31599562
773 + 31598789 = 31599562

Showing the first eight; more decompositions exist.
