Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534500, here are decompositions:

7 + 31534493 = 31534500
13 + 31534487 = 31534500
17 + 31534483 = 31534500
43 + 31534457 = 31534500
59 + 31534441 = 31534500
71 + 31534429 = 31534500
73 + 31534427 = 31534500
89 + 31534411 = 31534500

Showing the first eight; more decompositions exist.
