Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487554, here are decompositions:

47 + 487507 = 487554
73 + 487481 = 487554
83 + 487471 = 487554
97 + 487457 = 487554
107 + 487447 = 487554
127 + 487427 = 487554
131 + 487423 = 487554
157 + 487397 = 487554

Showing the first eight; more decompositions exist.
