Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154740, here are decompositions:

7 + 154733 = 154740
13 + 154727 = 154740
17 + 154723 = 154740
41 + 154699 = 154740
59 + 154681 = 154740
71 + 154669 = 154740
73 + 154667 = 154740
97 + 154643 = 154740

Showing the first eight; more decompositions exist.
