Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487932, here are decompositions:

41 + 487891 = 487932
43 + 487889 = 487932
59 + 487873 = 487932
89 + 487843 = 487932
101 + 487831 = 487932
103 + 487829 = 487932
113 + 487819 = 487932
139 + 487793 = 487932

Showing the first eight; more decompositions exist.
