Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154746, here are decompositions:

13 + 154733 = 154746
19 + 154727 = 154746
23 + 154723 = 154746
47 + 154699 = 154746
79 + 154667 = 154746
103 + 154643 = 154746
127 + 154619 = 154746
157 + 154589 = 154746

Showing the first eight; more decompositions exist.
