Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482686, here are decompositions:

3 + 31482683 = 31482686
19 + 31482667 = 31482686
43 + 31482643 = 31482686
73 + 31482613 = 31482686
127 + 31482559 = 31482686
337 + 31482349 = 31482686
349 + 31482337 = 31482686
379 + 31482307 = 31482686

Showing the first eight; more decompositions exist.
