Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500654, here are decompositions:

5 + 31500649 = 31500654
43 + 31500611 = 31500654
151 + 31500503 = 31500654
167 + 31500487 = 31500654
191 + 31500463 = 31500654
197 + 31500457 = 31500654
271 + 31500383 = 31500654
277 + 31500377 = 31500654

Showing the first eight; more decompositions exist.
