Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599944, here are decompositions:

3 + 31599941 = 31599944
31 + 31599913 = 31599944
43 + 31599901 = 31599944
67 + 31599877 = 31599944
73 + 31599871 = 31599944
163 + 31599781 = 31599944
241 + 31599703 = 31599944
457 + 31599487 = 31599944

Showing the first eight; more decompositions exist.
