Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476812, here are decompositions:

13 + 31476799 = 31476812
79 + 31476733 = 31476812
109 + 31476703 = 31476812
181 + 31476631 = 31476812
313 + 31476499 = 31476812
379 + 31476433 = 31476812
421 + 31476391 = 31476812
439 + 31476373 = 31476812

Showing the first eight; more decompositions exist.
