Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148446, here are decompositions:

7 + 148439 = 148446
17 + 148429 = 148446
43 + 148403 = 148446
47 + 148399 = 148446
59 + 148387 = 148446
79 + 148367 = 148446
107 + 148339 = 148446
167 + 148279 = 148446

Showing the first eight; more decompositions exist.
