Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487644, here are decompositions:

7 + 487637 = 487644
37 + 487607 = 487644
41 + 487603 = 487644
43 + 487601 = 487644
83 + 487561 = 487644
137 + 487507 = 487644
163 + 487481 = 487644
167 + 487477 = 487644

Showing the first eight; more decompositions exist.
