Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148458, here are decompositions:

19 + 148439 = 148458
29 + 148429 = 148458
47 + 148411 = 148458
59 + 148399 = 148458
71 + 148387 = 148458
97 + 148361 = 148458
127 + 148331 = 148458
157 + 148301 = 148458

Showing the first eight; more decompositions exist.
