Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536498, here are decompositions:

17 + 31536481 = 31536498
101 + 31536397 = 31536498
107 + 31536391 = 31536498
137 + 31536361 = 31536498
139 + 31536359 = 31536498
151 + 31536347 = 31536498
211 + 31536287 = 31536498
271 + 31536227 = 31536498

Showing the first eight; more decompositions exist.
