Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145356, here are decompositions:

7 + 145349 = 145356
53 + 145303 = 145356
67 + 145289 = 145356
73 + 145283 = 145356
89 + 145267 = 145356
97 + 145259 = 145356
103 + 145253 = 145356
137 + 145219 = 145356

Showing the first eight; more decompositions exist.
