Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553598, here are decompositions:

71 + 31553527 = 31553598
79 + 31553519 = 31553598
211 + 31553387 = 31553598
229 + 31553369 = 31553598
239 + 31553359 = 31553598
277 + 31553321 = 31553598
337 + 31553261 = 31553598
379 + 31553219 = 31553598

Showing the first eight; more decompositions exist.
