Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536148, here are decompositions:

47 + 31536101 = 31536148
131 + 31536017 = 31536148
167 + 31535981 = 31536148
239 + 31535909 = 31536148
269 + 31535879 = 31536148
317 + 31535831 = 31536148
401 + 31535747 = 31536148
431 + 31535717 = 31536148

Showing the first eight; more decompositions exist.
