Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54990, here are decompositions:

7 + 54983 = 54990
11 + 54979 = 54990
17 + 54973 = 54990
31 + 54959 = 54990
41 + 54949 = 54990
71 + 54919 = 54990
73 + 54917 = 54990
83 + 54907 = 54990

Showing the first eight; more decompositions exist.
