Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601322, here are decompositions:

59 + 31601263 = 31601322
131 + 31601191 = 31601322
223 + 31601099 = 31601322
239 + 31601083 = 31601322
271 + 31601051 = 31601322
281 + 31601041 = 31601322
353 + 31600969 = 31601322
439 + 31600883 = 31601322

Showing the first eight; more decompositions exist.
