Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601084, here are decompositions:

7 + 31601077 = 31601084
43 + 31601041 = 31601084
61 + 31601023 = 31601084
127 + 31600957 = 31601084
223 + 31600861 = 31601084
241 + 31600843 = 31601084
283 + 31600801 = 31601084
313 + 31600771 = 31601084

Showing the first eight; more decompositions exist.
