Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601394, here are decompositions:

37 + 31601357 = 31601394
47 + 31601347 = 31601394
53 + 31601341 = 31601394
127 + 31601267 = 31601394
131 + 31601263 = 31601394
191 + 31601203 = 31601394
257 + 31601137 = 31601394
311 + 31601083 = 31601394

Showing the first eight; more decompositions exist.
