Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619476, here are decompositions:

17 + 31619459 = 31619476
89 + 31619387 = 31619476
149 + 31619327 = 31619476
263 + 31619213 = 31619476
269 + 31619207 = 31619476
293 + 31619183 = 31619476
347 + 31619129 = 31619476
353 + 31619123 = 31619476

Showing the first eight; more decompositions exist.
