Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535108, here are decompositions:

97 + 31535011 = 31535108
109 + 31534999 = 31535108
127 + 31534981 = 31535108
229 + 31534879 = 31535108
277 + 31534831 = 31535108
307 + 31534801 = 31535108
379 + 31534729 = 31535108
439 + 31534669 = 31535108

Showing the first eight; more decompositions exist.
