Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55172, here are decompositions:

151 + 55021 = 55172
163 + 55009 = 55172
193 + 54979 = 55172
199 + 54973 = 55172
223 + 54949 = 55172
373 + 54799 = 55172
421 + 54751 = 55172
463 + 54709 = 55172

Showing the first eight; more decompositions exist.
