Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556592, here are decompositions:

103 + 31556489 = 31556592
113 + 31556479 = 31556592
131 + 31556461 = 31556592
211 + 31556381 = 31556592
239 + 31556353 = 31556592
251 + 31556341 = 31556592
269 + 31556323 = 31556592
283 + 31556309 = 31556592

Showing the first eight; more decompositions exist.
