Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477876, here are decompositions:

5 + 31477871 = 31477876
83 + 31477793 = 31477876
179 + 31477697 = 31477876
293 + 31477583 = 31477876
449 + 31477427 = 31477876
587 + 31477289 = 31477876
797 + 31477079 = 31477876
809 + 31477067 = 31477876

Showing the first eight; more decompositions exist.
