Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145650, here are decompositions:

7 + 145643 = 145650
13 + 145637 = 145650
17 + 145633 = 145650
47 + 145603 = 145650
61 + 145589 = 145650
73 + 145577 = 145650
101 + 145549 = 145650
103 + 145547 = 145650

Showing the first eight; more decompositions exist.
