Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577674, here are decompositions:

5 + 31577669 = 31577674
17 + 31577657 = 31577674
41 + 31577633 = 31577674
83 + 31577591 = 31577674
257 + 31577417 = 31577674
281 + 31577393 = 31577674
311 + 31577363 = 31577674
383 + 31577291 = 31577674

Showing the first eight; more decompositions exist.
