Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620476, here are decompositions:

3 + 31620473 = 31620476
67 + 31620409 = 31620476
79 + 31620397 = 31620476
337 + 31620139 = 31620476
367 + 31620109 = 31620476
409 + 31620067 = 31620476
439 + 31620037 = 31620476
457 + 31620019 = 31620476

Showing the first eight; more decompositions exist.
