Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496410, here are decompositions:

41 + 31496369 = 31496410
89 + 31496321 = 31496410
149 + 31496261 = 31496410
191 + 31496219 = 31496410
269 + 31496141 = 31496410
311 + 31496099 = 31496410
353 + 31496057 = 31496410
383 + 31496027 = 31496410

Showing the first eight; more decompositions exist.
