Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599494, here are decompositions:

7 + 31599487 = 31599494
181 + 31599313 = 31599494
337 + 31599157 = 31599494
541 + 31598953 = 31599494
547 + 31598947 = 31599494
571 + 31598923 = 31599494
607 + 31598887 = 31599494
631 + 31598863 = 31599494

Showing the first eight; more decompositions exist.
