Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563598, here are decompositions:

5 + 31563593 = 31563598
29 + 31563569 = 31563598
47 + 31563551 = 31563598
71 + 31563527 = 31563598
107 + 31563491 = 31563598
167 + 31563431 = 31563598
197 + 31563401 = 31563598
239 + 31563359 = 31563598

Showing the first eight; more decompositions exist.
