Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566598, here are decompositions:

71 + 31566527 = 31566598
101 + 31566497 = 31566598
149 + 31566449 = 31566598
251 + 31566347 = 31566598
269 + 31566329 = 31566598
281 + 31566317 = 31566598
311 + 31566287 = 31566598
347 + 31566251 = 31566598

Showing the first eight; more decompositions exist.
