Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535362, here are decompositions:

41 + 31535321 = 31535362
149 + 31535213 = 31535362
179 + 31535183 = 31535362
191 + 31535171 = 31535362
239 + 31535123 = 31535362
281 + 31535081 = 31535362
401 + 31534961 = 31535362
449 + 31534913 = 31535362

Showing the first eight; more decompositions exist.
