Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535030, here are decompositions:

19 + 31535011 = 31535030
31 + 31534999 = 31535030
151 + 31534879 = 31535030
157 + 31534873 = 31535030
199 + 31534831 = 31535030
211 + 31534819 = 31535030
229 + 31534801 = 31535030
277 + 31534753 = 31535030

Showing the first eight; more decompositions exist.
