Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477046, here are decompositions:

19 + 31477027 = 31477046
193 + 31476853 = 31477046
199 + 31476847 = 31477046
313 + 31476733 = 31477046
439 + 31476607 = 31477046
499 + 31476547 = 31477046
547 + 31476499 = 31477046
613 + 31476433 = 31477046

Showing the first eight; more decompositions exist.
