Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599956, here are decompositions:

43 + 31599913 = 31599956
79 + 31599877 = 31599956
97 + 31599859 = 31599956
229 + 31599727 = 31599956
307 + 31599649 = 31599956
457 + 31599499 = 31599956
607 + 31599349 = 31599956
643 + 31599313 = 31599956

Showing the first eight; more decompositions exist.
