Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536706, here are decompositions:

167 + 31536539 = 31536706
347 + 31536359 = 31536706
353 + 31536353 = 31536706
359 + 31536347 = 31536706
419 + 31536287 = 31536706
479 + 31536227 = 31536706
503 + 31536203 = 31536706
653 + 31536053 = 31536706

Showing the first eight; more decompositions exist.
