Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149470, here are decompositions:

11 + 149459 = 149470
29 + 149441 = 149470
47 + 149423 = 149470
53 + 149417 = 149470
59 + 149411 = 149470
71 + 149399 = 149470
89 + 149381 = 149470
137 + 149333 = 149470

Showing the first eight; more decompositions exist.
