Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599806, here are decompositions:

79 + 31599727 = 31599806
103 + 31599703 = 31599806
157 + 31599649 = 31599806
307 + 31599499 = 31599806
367 + 31599439 = 31599806
457 + 31599349 = 31599806
499 + 31599307 = 31599806
547 + 31599259 = 31599806

Showing the first eight; more decompositions exist.
