Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166042, here are decompositions:

11 + 166031 = 166042
29 + 166013 = 166042
59 + 165983 = 166042
101 + 165941 = 166042
263 + 165779 = 166042
293 + 165749 = 166042
389 + 165653 = 166042
431 + 165611 = 166042

Showing the first eight; more decompositions exist.
