Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487562, here are decompositions:

73 + 487489 = 487562
139 + 487423 = 487562
181 + 487381 = 487562
199 + 487363 = 487562
349 + 487213 = 487562
379 + 487183 = 487562
463 + 487099 = 487562
541 + 487021 = 487562

Showing the first eight; more decompositions exist.
