Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536140, here are decompositions:

43 + 31536097 = 31536140
79 + 31536061 = 31536140
157 + 31535983 = 31536140
193 + 31535947 = 31536140
199 + 31535941 = 31536140
313 + 31535827 = 31536140
331 + 31535809 = 31536140
547 + 31535593 = 31536140

Showing the first eight; more decompositions exist.
