Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151392, here are decompositions:

11 + 151381 = 151392
13 + 151379 = 151392
53 + 151339 = 151392
89 + 151303 = 151392
103 + 151289 = 151392
113 + 151279 = 151392
139 + 151253 = 151392
149 + 151243 = 151392

Showing the first eight; more decompositions exist.
