Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482910, here are decompositions:

3 + 31482907 = 31482910
71 + 31482839 = 31482910
89 + 31482821 = 31482910
131 + 31482779 = 31482910
149 + 31482761 = 31482910
167 + 31482743 = 31482910
227 + 31482683 = 31482910
269 + 31482641 = 31482910

Showing the first eight; more decompositions exist.
