Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189740, here are decompositions:

7 + 189733 = 189740
43 + 189697 = 189740
79 + 189661 = 189740
97 + 189643 = 189740
127 + 189613 = 189740
157 + 189583 = 189740
181 + 189559 = 189740
193 + 189547 = 189740

Showing the first eight; more decompositions exist.
