Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482876, here are decompositions:

17 + 31482859 = 31482876
37 + 31482839 = 31482876
43 + 31482833 = 31482876
53 + 31482823 = 31482876
97 + 31482779 = 31482876
167 + 31482709 = 31482876
193 + 31482683 = 31482876
233 + 31482643 = 31482876

Showing the first eight; more decompositions exist.
