Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151740, here are decompositions:

7 + 151733 = 151740
11 + 151729 = 151740
23 + 151717 = 151740
37 + 151703 = 151740
47 + 151693 = 151740
53 + 151687 = 151740
59 + 151681 = 151740
67 + 151673 = 151740

Showing the first eight; more decompositions exist.
