Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598914, here are decompositions:

3 + 31598911 = 31598914
5 + 31598909 = 31598914
41 + 31598873 = 31598914
47 + 31598867 = 31598914
131 + 31598783 = 31598914
197 + 31598717 = 31598914
227 + 31598687 = 31598914
401 + 31598513 = 31598914

Showing the first eight; more decompositions exist.
