Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536684, here are decompositions:

71 + 31536613 = 31536684
163 + 31536521 = 31536684
281 + 31536403 = 31536684
293 + 31536391 = 31536684
331 + 31536353 = 31536684
337 + 31536347 = 31536684
397 + 31536287 = 31536684
457 + 31536227 = 31536684

Showing the first eight; more decompositions exist.
