Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166862, here are decompositions:

13 + 166849 = 166862
19 + 166843 = 166862
79 + 166783 = 166862
139 + 166723 = 166862
193 + 166669 = 166862
433 + 166429 = 166862
463 + 166399 = 166862
499 + 166363 = 166862

Showing the first eight; more decompositions exist.
