Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535000, here are decompositions:

19 + 31534981 = 31535000
127 + 31534873 = 31535000
181 + 31534819 = 31535000
199 + 31534801 = 31535000
271 + 31534729 = 31535000
331 + 31534669 = 31535000
349 + 31534651 = 31535000
439 + 31534561 = 31535000

Showing the first eight; more decompositions exist.
