Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601400, here are decompositions:

7 + 31601393 = 31601400
41 + 31601359 = 31601400
43 + 31601357 = 31601400
53 + 31601347 = 31601400
59 + 31601341 = 31601400
137 + 31601263 = 31601400
197 + 31601203 = 31601400
263 + 31601137 = 31601400

Showing the first eight; more decompositions exist.
