Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577934, here are decompositions:

5 + 31577929 = 31577934
137 + 31577797 = 31577934
151 + 31577783 = 31577934
277 + 31577657 = 31577934
347 + 31577587 = 31577934
461 + 31577473 = 31577934
463 + 31577471 = 31577934
541 + 31577393 = 31577934

Showing the first eight; more decompositions exist.
