Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536144, here are decompositions:

43 + 31536101 = 31536144
47 + 31536097 = 31536144
83 + 31536061 = 31536144
127 + 31536017 = 31536144
163 + 31535981 = 31536144
197 + 31535947 = 31536144
313 + 31535831 = 31536144
317 + 31535827 = 31536144

Showing the first eight; more decompositions exist.
