Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145590, here are decompositions:

13 + 145577 = 145590
41 + 145549 = 145590
43 + 145547 = 145590
47 + 145543 = 145590
59 + 145531 = 145590
73 + 145517 = 145590
79 + 145511 = 145590
89 + 145501 = 145590

Showing the first eight; more decompositions exist.
