Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148170, here are decompositions:

13 + 148157 = 148170
17 + 148153 = 148170
19 + 148151 = 148170
23 + 148147 = 148170
31 + 148139 = 148170
47 + 148123 = 148170
79 + 148091 = 148170
97 + 148073 = 148170

Showing the first eight; more decompositions exist.
