Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149454, here are decompositions:

13 + 149441 = 149454
31 + 149423 = 149454
37 + 149417 = 149454
43 + 149411 = 149454
61 + 149393 = 149454
73 + 149381 = 149454
83 + 149371 = 149454
103 + 149351 = 149454

Showing the first eight; more decompositions exist.
