Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468840, here are decompositions:

19 + 468821 = 468840
23 + 468817 = 468840
37 + 468803 = 468840
59 + 468781 = 468840
67 + 468773 = 468840
79 + 468761 = 468840
101 + 468739 = 468840
103 + 468737 = 468840

Showing the first eight; more decompositions exist.
