Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536126, here are decompositions:

29 + 31536097 = 31536126
73 + 31536053 = 31536126
107 + 31536019 = 31536126
109 + 31536017 = 31536126
179 + 31535947 = 31536126
317 + 31535809 = 31536126
373 + 31535753 = 31536126
379 + 31535747 = 31536126

Showing the first eight; more decompositions exist.
