Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536964, here are decompositions:

5 + 31536959 = 31536964
47 + 31536917 = 31536964
101 + 31536863 = 31536964
191 + 31536773 = 31536964
233 + 31536731 = 31536964
257 + 31536707 = 31536964
443 + 31536521 = 31536964
617 + 31536347 = 31536964

Showing the first eight; more decompositions exist.
