Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577606, here are decompositions:

13 + 31577593 = 31577606
19 + 31577587 = 31577606
79 + 31577527 = 31577606
97 + 31577509 = 31577606
223 + 31577383 = 31577606
283 + 31577323 = 31577606
337 + 31577269 = 31577606
367 + 31577239 = 31577606

Showing the first eight; more decompositions exist.
