Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482922, here are decompositions:

83 + 31482839 = 31482922
89 + 31482833 = 31482922
101 + 31482821 = 31482922
179 + 31482743 = 31482922
239 + 31482683 = 31482922
281 + 31482641 = 31482922
353 + 31482569 = 31482922
521 + 31482401 = 31482922

Showing the first eight; more decompositions exist.
