Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151398, here are decompositions:

7 + 151391 = 151398
17 + 151381 = 151398
19 + 151379 = 151398
41 + 151357 = 151398
59 + 151339 = 151398
61 + 151337 = 151398
109 + 151289 = 151398
151 + 151247 = 151398

Showing the first eight; more decompositions exist.
