Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520674, here are decompositions:

47 + 31520627 = 31520674
137 + 31520537 = 31520674
191 + 31520483 = 31520674
257 + 31520417 = 31520674
281 + 31520393 = 31520674
431 + 31520243 = 31520674
503 + 31520171 = 31520674
557 + 31520117 = 31520674

Showing the first eight; more decompositions exist.
