Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601684, here are decompositions:

13 + 31601671 = 31601684
157 + 31601527 = 31601684
211 + 31601473 = 31601684
277 + 31601407 = 31601684
337 + 31601347 = 31601684
421 + 31601263 = 31601684
547 + 31601137 = 31601684
601 + 31601083 = 31601684

Showing the first eight; more decompositions exist.
