Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146538, here are decompositions:

11 + 146527 = 146538
17 + 146521 = 146538
19 + 146519 = 146538
61 + 146477 = 146538
89 + 146449 = 146538
101 + 146437 = 146538
131 + 146407 = 146538
149 + 146389 = 146538

Showing the first eight; more decompositions exist.
