Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186492, here are decompositions:

11 + 186481 = 186492
13 + 186479 = 186492
23 + 186469 = 186492
41 + 186451 = 186492
73 + 186419 = 186492
101 + 186391 = 186492
113 + 186379 = 186492
149 + 186343 = 186492

Showing the first eight; more decompositions exist.
