Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601948, here are decompositions:

67 + 31601881 = 31601948
139 + 31601809 = 31601948
181 + 31601767 = 31601948
241 + 31601707 = 31601948
277 + 31601671 = 31601948
379 + 31601569 = 31601948
397 + 31601551 = 31601948
409 + 31601539 = 31601948

Showing the first eight; more decompositions exist.
