Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520366, here are decompositions:

13 + 31520353 = 31520366
67 + 31520299 = 31520366
193 + 31520173 = 31520366
277 + 31520089 = 31520366
307 + 31520059 = 31520366
337 + 31520029 = 31520366
349 + 31520017 = 31520366
379 + 31519987 = 31520366

Showing the first eight; more decompositions exist.
