Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487566, here are decompositions:

5 + 487561 = 487566
59 + 487507 = 487566
89 + 487477 = 487566
97 + 487469 = 487566
103 + 487463 = 487566
109 + 487457 = 487566
137 + 487429 = 487566
139 + 487427 = 487566

Showing the first eight; more decompositions exist.
