Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482934, here are decompositions:

101 + 31482833 = 31482934
113 + 31482821 = 31482934
173 + 31482761 = 31482934
191 + 31482743 = 31482934
227 + 31482707 = 31482934
251 + 31482683 = 31482934
293 + 31482641 = 31482934
317 + 31482617 = 31482934

Showing the first eight; more decompositions exist.
