Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535276, here are decompositions:

13 + 31535263 = 31535276
43 + 31535233 = 31535276
103 + 31535173 = 31535276
163 + 31535113 = 31535276
193 + 31535083 = 31535276
277 + 31534999 = 31535276
397 + 31534879 = 31535276
457 + 31534819 = 31535276

Showing the first eight; more decompositions exist.
