Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519952, here are decompositions:

19 + 31519933 = 31519952
43 + 31519909 = 31519952
109 + 31519843 = 31519952
151 + 31519801 = 31519952
199 + 31519753 = 31519952
241 + 31519711 = 31519952
421 + 31519531 = 31519952
433 + 31519519 = 31519952

Showing the first eight; more decompositions exist.
