Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500590, here are decompositions:

31 + 31500559 = 31500590
61 + 31500529 = 31500590
103 + 31500487 = 31500590
127 + 31500463 = 31500590
139 + 31500451 = 31500590
211 + 31500379 = 31500590
223 + 31500367 = 31500590
229 + 31500361 = 31500590

Showing the first eight; more decompositions exist.
