Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55072, here are decompositions:

11 + 55061 = 55072
23 + 55049 = 55072
71 + 55001 = 55072
89 + 54983 = 55072
113 + 54959 = 55072
131 + 54941 = 55072
191 + 54881 = 55072
239 + 54833 = 55072

Showing the first eight; more decompositions exist.
