Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601060, here are decompositions:

19 + 31601041 = 31601060
37 + 31601023 = 31601060
67 + 31600993 = 31601060
103 + 31600957 = 31601060
199 + 31600861 = 31601060
277 + 31600783 = 31601060
307 + 31600753 = 31601060
367 + 31600693 = 31601060

Showing the first eight; more decompositions exist.
