Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487542, here are decompositions:

53 + 487489 = 487542
61 + 487481 = 487542
71 + 487471 = 487542
73 + 487469 = 487542
79 + 487463 = 487542
113 + 487429 = 487542
151 + 487391 = 487542
179 + 487363 = 487542

Showing the first eight; more decompositions exist.
