Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67890, here are decompositions:

7 + 67883 = 67890
23 + 67867 = 67890
37 + 67853 = 67890
47 + 67843 = 67890
61 + 67829 = 67890
71 + 67819 = 67890
83 + 67807 = 67890
89 + 67801 = 67890

Showing the first eight; more decompositions exist.
