Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48990, here are decompositions:

17 + 48973 = 48990
37 + 48953 = 48990
43 + 48947 = 48990
83 + 48907 = 48990
101 + 48889 = 48990
107 + 48883 = 48990
131 + 48859 = 48990
167 + 48823 = 48990

Showing the first eight; more decompositions exist.
