Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500834, here are decompositions:

17 + 31500817 = 31500834
37 + 31500797 = 31500834
41 + 31500793 = 31500834
61 + 31500773 = 31500834
67 + 31500767 = 31500834
97 + 31500737 = 31500834
223 + 31500611 = 31500834
331 + 31500503 = 31500834

Showing the first eight; more decompositions exist.
