Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576674, here are decompositions:

163 + 31576511 = 31576674
191 + 31576483 = 31576674
197 + 31576477 = 31576674
257 + 31576417 = 31576674
263 + 31576411 = 31576674
271 + 31576403 = 31576674
307 + 31576367 = 31576674
421 + 31576253 = 31576674

Showing the first eight; more decompositions exist.
