Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487842, here are decompositions:

11 + 487831 = 487842
13 + 487829 = 487842
23 + 487819 = 487842
31 + 487811 = 487842
53 + 487789 = 487842
59 + 487783 = 487842
73 + 487769 = 487842
101 + 487741 = 487842

Showing the first eight; more decompositions exist.
