Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500454, here are decompositions:

3 + 31500451 = 31500454
47 + 31500407 = 31500454
71 + 31500383 = 31500454
101 + 31500353 = 31500454
173 + 31500281 = 31500454
191 + 31500263 = 31500454
233 + 31500221 = 31500454
257 + 31500197 = 31500454

Showing the first eight; more decompositions exist.
