Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498874, here are decompositions:

7 + 31498867 = 31498874
37 + 31498837 = 31498874
61 + 31498813 = 31498874
283 + 31498591 = 31498874
601 + 31498273 = 31498874
661 + 31498213 = 31498874
751 + 31498123 = 31498874
787 + 31498087 = 31498874

Showing the first eight; more decompositions exist.
