Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535366, here are decompositions:

103 + 31535263 = 31535366
139 + 31535227 = 31535366
193 + 31535173 = 31535366
223 + 31535143 = 31535366
283 + 31535083 = 31535366
307 + 31535059 = 31535366
367 + 31534999 = 31535366
487 + 31534879 = 31535366

Showing the first eight; more decompositions exist.
