Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186740, here are decompositions:

7 + 186733 = 186740
13 + 186727 = 186740
31 + 186709 = 186740
61 + 186679 = 186740
139 + 186601 = 186740
157 + 186583 = 186740
271 + 186469 = 186740
349 + 186391 = 186740

Showing the first eight; more decompositions exist.
