Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600532, here are decompositions:

3 + 31600529 = 31600532
79 + 31600453 = 31600532
109 + 31600423 = 31600532
199 + 31600333 = 31600532
241 + 31600291 = 31600532
331 + 31600201 = 31600532
433 + 31600099 = 31600532
619 + 31599913 = 31600532

Showing the first eight; more decompositions exist.
