Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484882, here are decompositions:

19 + 31484863 = 31484882
43 + 31484839 = 31484882
61 + 31484821 = 31484882
313 + 31484569 = 31484882
349 + 31484533 = 31484882
379 + 31484503 = 31484882
421 + 31484461 = 31484882
433 + 31484449 = 31484882

Showing the first eight; more decompositions exist.
