Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601294, here are decompositions:

31 + 31601263 = 31601294
103 + 31601191 = 31601294
157 + 31601137 = 31601294
211 + 31601083 = 31601294
271 + 31601023 = 31601294
337 + 31600957 = 31601294
433 + 31600861 = 31601294
523 + 31600771 = 31601294

Showing the first eight; more decompositions exist.
