Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505674, here are decompositions:

17 + 31505657 = 31505674
41 + 31505633 = 31505674
107 + 31505567 = 31505674
173 + 31505501 = 31505674
227 + 31505447 = 31505674
293 + 31505381 = 31505674
353 + 31505321 = 31505674
461 + 31505213 = 31505674

Showing the first eight; more decompositions exist.
