Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453500, here are decompositions:

17 + 31453483 = 31453500
37 + 31453463 = 31453500
53 + 31453447 = 31453500
73 + 31453427 = 31453500
79 + 31453421 = 31453500
107 + 31453393 = 31453500
109 + 31453391 = 31453500
139 + 31453361 = 31453500

Showing the first eight; more decompositions exist.
