Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535252, here are decompositions:

19 + 31535233 = 31535252
79 + 31535173 = 31535252
109 + 31535143 = 31535252
139 + 31535113 = 31535252
193 + 31535059 = 31535252
241 + 31535011 = 31535252
271 + 31534981 = 31535252
373 + 31534879 = 31535252

Showing the first eight; more decompositions exist.
