Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477016, here are decompositions:

163 + 31476853 = 31477016
283 + 31476733 = 31477016
313 + 31476703 = 31477016
409 + 31476607 = 31477016
499 + 31476517 = 31477016
643 + 31476373 = 31477016
673 + 31476343 = 31477016
733 + 31476283 = 31477016

Showing the first eight; more decompositions exist.
