Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145506, here are decompositions:

5 + 145501 = 145506
19 + 145487 = 145506
29 + 145477 = 145506
43 + 145463 = 145506
47 + 145459 = 145506
73 + 145433 = 145506
83 + 145423 = 145506
89 + 145417 = 145506

Showing the first eight; more decompositions exist.
