Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601976, here are decompositions:

53 + 31601923 = 31601976
79 + 31601897 = 31601976
103 + 31601873 = 31601976
113 + 31601863 = 31601976
127 + 31601849 = 31601976
139 + 31601837 = 31601976
157 + 31601819 = 31601976
167 + 31601809 = 31601976

Showing the first eight; more decompositions exist.
