Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536184, here are decompositions:

23 + 31536161 = 31536184
83 + 31536101 = 31536184
131 + 31536053 = 31536184
167 + 31536017 = 31536184
353 + 31535831 = 31536184
431 + 31535753 = 31536184
443 + 31535741 = 31536184
467 + 31535717 = 31536184

Showing the first eight; more decompositions exist.
