Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500754, here are decompositions:

17 + 31500737 = 31500754
41 + 31500713 = 31500754
53 + 31500701 = 31500754
251 + 31500503 = 31500754
347 + 31500407 = 31500754
401 + 31500353 = 31500754
491 + 31500263 = 31500754
557 + 31500197 = 31500754

Showing the first eight; more decompositions exist.
