Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487436, here are decompositions:

7 + 487429 = 487436
13 + 487423 = 487436
73 + 487363 = 487436
223 + 487213 = 487436
337 + 487099 = 487436
379 + 487057 = 487436
487 + 486949 = 487436
619 + 486817 = 487436

Showing the first eight; more decompositions exist.
