Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487912, here are decompositions:

23 + 487889 = 487912
83 + 487829 = 487912
101 + 487811 = 487912
179 + 487733 = 487912
263 + 487649 = 487912
311 + 487601 = 487912
431 + 487481 = 487912
443 + 487469 = 487912

Showing the first eight; more decompositions exist.
