Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599952, here are decompositions:

11 + 31599941 = 31599952
23 + 31599929 = 31599952
179 + 31599773 = 31599952
191 + 31599761 = 31599952
269 + 31599683 = 31599952
281 + 31599671 = 31599952
353 + 31599599 = 31599952
389 + 31599563 = 31599952

Showing the first eight; more decompositions exist.
