Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536100, here are decompositions:

3 + 31536097 = 31536100
47 + 31536053 = 31536100
83 + 31536017 = 31536100
191 + 31535909 = 31536100
269 + 31535831 = 31536100
347 + 31535753 = 31536100
353 + 31535747 = 31536100
359 + 31535741 = 31536100

Showing the first eight; more decompositions exist.
