Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601534, here are decompositions:

7 + 31601527 = 31601534
61 + 31601473 = 31601534
127 + 31601407 = 31601534
193 + 31601341 = 31601534
271 + 31601263 = 31601534
331 + 31601203 = 31601534
397 + 31601137 = 31601534
457 + 31601077 = 31601534

Showing the first eight; more decompositions exist.
