Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55166, here are decompositions:

3 + 55163 = 55166
19 + 55147 = 55166
109 + 55057 = 55166
157 + 55009 = 55166
193 + 54973 = 55166
337 + 54829 = 55166
367 + 54799 = 55166
379 + 54787 = 55166

Showing the first eight; more decompositions exist.
