Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536526, here are decompositions:

5 + 31536521 = 31536526
167 + 31536359 = 31536526
173 + 31536353 = 31536526
179 + 31536347 = 31536526
233 + 31536293 = 31536526
239 + 31536287 = 31536526
509 + 31536017 = 31536526
587 + 31535939 = 31536526

Showing the first eight; more decompositions exist.
