Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601964, here are decompositions:

41 + 31601923 = 31601964
67 + 31601897 = 31601964
73 + 31601891 = 31601964
83 + 31601881 = 31601964
101 + 31601863 = 31601964
127 + 31601837 = 31601964
181 + 31601783 = 31601964
197 + 31601767 = 31601964

Showing the first eight; more decompositions exist.
