Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508926, here are decompositions:

5 + 31508921 = 31508926
83 + 31508843 = 31508926
179 + 31508747 = 31508926
269 + 31508657 = 31508926
347 + 31508579 = 31508926
359 + 31508567 = 31508926
419 + 31508507 = 31508926
509 + 31508417 = 31508926

Showing the first eight; more decompositions exist.
