Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607674, here are decompositions:

3 + 31607671 = 31607674
227 + 31607447 = 31607674
251 + 31607423 = 31607674
311 + 31607363 = 31607674
317 + 31607357 = 31607674
347 + 31607327 = 31607674
383 + 31607291 = 31607674
467 + 31607207 = 31607674

Showing the first eight; more decompositions exist.
