Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481674, here are decompositions:

53 + 31481621 = 31481674
83 + 31481591 = 31481674
131 + 31481543 = 31481674
167 + 31481507 = 31481674
197 + 31481477 = 31481674
281 + 31481393 = 31481674
353 + 31481321 = 31481674
443 + 31481231 = 31481674

Showing the first eight; more decompositions exist.
