Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536670, here are decompositions:

41 + 31536629 = 31536670
131 + 31536539 = 31536670
149 + 31536521 = 31536670
311 + 31536359 = 31536670
317 + 31536353 = 31536670
383 + 31536287 = 31536670
443 + 31536227 = 31536670
467 + 31536203 = 31536670

Showing the first eight; more decompositions exist.
