Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535084, here are decompositions:

3 + 31535081 = 31535084
73 + 31535011 = 31535084
103 + 31534981 = 31535084
211 + 31534873 = 31535084
283 + 31534801 = 31535084
331 + 31534753 = 31535084
433 + 31534651 = 31535084
487 + 31534597 = 31535084

Showing the first eight; more decompositions exist.
