Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601066, here are decompositions:

43 + 31601023 = 31601066
73 + 31600993 = 31601066
97 + 31600969 = 31601066
109 + 31600957 = 31601066
223 + 31600843 = 31601066
283 + 31600783 = 31601066
313 + 31600753 = 31601066
349 + 31600717 = 31601066

Showing the first eight; more decompositions exist.
