Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598926, here are decompositions:

3 + 31598923 = 31598926
17 + 31598909 = 31598926
53 + 31598873 = 31598926
59 + 31598867 = 31598926
137 + 31598789 = 31598926
173 + 31598753 = 31598926
239 + 31598687 = 31598926
257 + 31598669 = 31598926

Showing the first eight; more decompositions exist.
