Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599950, here are decompositions:

37 + 31599913 = 31599950
73 + 31599877 = 31599950
79 + 31599871 = 31599950
127 + 31599823 = 31599950
139 + 31599811 = 31599950
223 + 31599727 = 31599950
397 + 31599553 = 31599950
463 + 31599487 = 31599950

Showing the first eight; more decompositions exist.
