Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482832, here are decompositions:

11 + 31482821 = 31482832
53 + 31482779 = 31482832
71 + 31482761 = 31482832
89 + 31482743 = 31482832
149 + 31482683 = 31482832
191 + 31482641 = 31482832
233 + 31482599 = 31482832
263 + 31482569 = 31482832

Showing the first eight; more decompositions exist.
