Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145560, here are decompositions:

11 + 145549 = 145560
13 + 145547 = 145560
17 + 145543 = 145560
29 + 145531 = 145560
43 + 145517 = 145560
47 + 145513 = 145560
59 + 145501 = 145560
73 + 145487 = 145560

Showing the first eight; more decompositions exist.
