Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500674, here are decompositions:

211 + 31500463 = 31500674
223 + 31500451 = 31500674
307 + 31500367 = 31500674
313 + 31500361 = 31500674
487 + 31500187 = 31500674
811 + 31499863 = 31500674
1291 + 31499383 = 31500674
1303 + 31499371 = 31500674

Showing the first eight; more decompositions exist.
