Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599752, here are decompositions:

103 + 31599649 = 31599752
199 + 31599553 = 31599752
313 + 31599439 = 31599752
439 + 31599313 = 31599752
829 + 31598923 = 31599752
1051 + 31598701 = 31599752
1069 + 31598683 = 31599752
1231 + 31598521 = 31599752

Showing the first eight; more decompositions exist.
