Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146660, here are decompositions:

13 + 146647 = 146660
43 + 146617 = 146660
79 + 146581 = 146660
97 + 146563 = 146660
139 + 146521 = 146660
211 + 146449 = 146660
223 + 146437 = 146660
271 + 146389 = 146660

Showing the first eight; more decompositions exist.
