Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476620, here are decompositions:

13 + 31476607 = 31476620
73 + 31476547 = 31476620
103 + 31476517 = 31476620
163 + 31476457 = 31476620
229 + 31476391 = 31476620
271 + 31476349 = 31476620
277 + 31476343 = 31476620
337 + 31476283 = 31476620

Showing the first eight; more decompositions exist.
