Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51990, here are decompositions:

13 + 51977 = 51990
17 + 51973 = 51990
19 + 51971 = 51990
41 + 51949 = 51990
61 + 51929 = 51990
83 + 51907 = 51990
97 + 51893 = 51990
131 + 51859 = 51990

Showing the first eight; more decompositions exist.
