Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601600, here are decompositions:

31 + 31601569 = 31601600
61 + 31601539 = 31601600
73 + 31601527 = 31601600
127 + 31601473 = 31601600
193 + 31601407 = 31601600
241 + 31601359 = 31601600
337 + 31601263 = 31601600
397 + 31601203 = 31601600

Showing the first eight; more decompositions exist.
