Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601042, here are decompositions:

19 + 31601023 = 31601042
73 + 31600969 = 31601042
181 + 31600861 = 31601042
199 + 31600843 = 31601042
241 + 31600801 = 31601042
271 + 31600771 = 31601042
349 + 31600693 = 31601042
373 + 31600669 = 31601042

Showing the first eight; more decompositions exist.
