Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601926, here are decompositions:

3 + 31601923 = 31601926
29 + 31601897 = 31601926
53 + 31601873 = 31601926
89 + 31601837 = 31601926
107 + 31601819 = 31601926
227 + 31601699 = 31601926
359 + 31601567 = 31601926
509 + 31601417 = 31601926

Showing the first eight; more decompositions exist.
