Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184840, here are decompositions:

3 + 184837 = 184840
11 + 184829 = 184840
17 + 184823 = 184840
107 + 184733 = 184840
113 + 184727 = 184840
137 + 184703 = 184840
191 + 184649 = 184840
233 + 184607 = 184840

Showing the first eight; more decompositions exist.
