Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184890, here are decompositions:

11 + 184879 = 184890
31 + 184859 = 184890
47 + 184843 = 184890
53 + 184837 = 184890
59 + 184831 = 184890
61 + 184829 = 184890
67 + 184823 = 184890
113 + 184777 = 184890

Showing the first eight; more decompositions exist.
