Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2054, here are decompositions:

37 + 2017 = 2054
43 + 2011 = 2054
61 + 1993 = 2054
67 + 1987 = 2054
103 + 1951 = 2054
181 + 1873 = 2054
193 + 1861 = 2054
223 + 1831 = 2054

Showing the first eight; more decompositions exist.
