Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145326, here are decompositions:

19 + 145307 = 145326
23 + 145303 = 145326
37 + 145289 = 145326
43 + 145283 = 145326
59 + 145267 = 145326
67 + 145259 = 145326
73 + 145253 = 145326
107 + 145219 = 145326

Showing the first eight; more decompositions exist.
