Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487976, here are decompositions:

3 + 487973 = 487976
43 + 487933 = 487976
79 + 487897 = 487976
103 + 487873 = 487976
157 + 487819 = 487976
193 + 487783 = 487976
373 + 487603 = 487976
487 + 487489 = 487976

Showing the first eight; more decompositions exist.
