Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154460, here are decompositions:

37 + 154423 = 154460
43 + 154417 = 154460
73 + 154387 = 154460
109 + 154351 = 154460
127 + 154333 = 154460
139 + 154321 = 154460
157 + 154303 = 154460
181 + 154279 = 154460

Showing the first eight; more decompositions exist.
