Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601952, here are decompositions:

29 + 31601923 = 31601952
61 + 31601891 = 31601952
71 + 31601881 = 31601952
79 + 31601873 = 31601952
89 + 31601863 = 31601952
103 + 31601849 = 31601952
229 + 31601723 = 31601952
241 + 31601711 = 31601952

Showing the first eight; more decompositions exist.
