Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476446, here are decompositions:

13 + 31476433 = 31476446
73 + 31476373 = 31476446
97 + 31476349 = 31476446
103 + 31476343 = 31476446
163 + 31476283 = 31476446
277 + 31476169 = 31476446
349 + 31476097 = 31476446
373 + 31476073 = 31476446

Showing the first eight; more decompositions exist.
