Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186498, here are decompositions:

17 + 186481 = 186498
19 + 186479 = 186498
29 + 186469 = 186498
47 + 186451 = 186498
61 + 186437 = 186498
79 + 186419 = 186498
101 + 186397 = 186498
107 + 186391 = 186498

Showing the first eight; more decompositions exist.
