Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476722, here are decompositions:

19 + 31476703 = 31476722
31 + 31476691 = 31476722
223 + 31476499 = 31476722
271 + 31476451 = 31476722
331 + 31476391 = 31476722
349 + 31476373 = 31476722
373 + 31476349 = 31476722
379 + 31476343 = 31476722

Showing the first eight; more decompositions exist.
