Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166718, here are decompositions:

61 + 166657 = 166718
109 + 166609 = 166718
151 + 166567 = 166718
157 + 166561 = 166718
367 + 166351 = 166718
421 + 166297 = 166718
499 + 166219 = 166718
571 + 166147 = 166718

Showing the first eight; more decompositions exist.
