Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154452, here are decompositions:

13 + 154439 = 154452
29 + 154423 = 154452
43 + 154409 = 154452
79 + 154373 = 154452
83 + 154369 = 154452
101 + 154351 = 154452
113 + 154339 = 154452
131 + 154321 = 154452

Showing the first eight; more decompositions exist.
