Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151434, here are decompositions:

5 + 151429 = 151434
11 + 151423 = 151434
37 + 151397 = 151434
43 + 151391 = 151434
53 + 151381 = 151434
97 + 151337 = 151434
131 + 151303 = 151434
181 + 151253 = 151434

Showing the first eight; more decompositions exist.
