Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21054, here are decompositions:

23 + 21031 = 21054
31 + 21023 = 21054
37 + 21017 = 21054
41 + 21013 = 21054
43 + 21011 = 21054
53 + 21001 = 21054
71 + 20983 = 21054
73 + 20981 = 21054

Showing the first eight; more decompositions exist.
