Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166488, here are decompositions:

17 + 166471 = 166488
31 + 166457 = 166488
59 + 166429 = 166488
71 + 166417 = 166488
79 + 166409 = 166488
89 + 166399 = 166488
131 + 166357 = 166488
137 + 166351 = 166488

Showing the first eight; more decompositions exist.
