Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601956, here are decompositions:

59 + 31601897 = 31601956
83 + 31601873 = 31601956
107 + 31601849 = 31601956
137 + 31601819 = 31601956
173 + 31601783 = 31601956
233 + 31601723 = 31601956
257 + 31601699 = 31601956
389 + 31601567 = 31601956

Showing the first eight; more decompositions exist.
