Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487832, here are decompositions:

3 + 487829 = 487832
13 + 487819 = 487832
43 + 487789 = 487832
151 + 487681 = 487832
181 + 487651 = 487832
229 + 487603 = 487832
271 + 487561 = 487832
409 + 487423 = 487832

Showing the first eight; more decompositions exist.
