Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482850, here are decompositions:

11 + 31482839 = 31482850
17 + 31482833 = 31482850
29 + 31482821 = 31482850
71 + 31482779 = 31482850
89 + 31482761 = 31482850
107 + 31482743 = 31482850
167 + 31482683 = 31482850
233 + 31482617 = 31482850

Showing the first eight; more decompositions exist.
