Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4990, here are decompositions:

3 + 4987 = 4990
17 + 4973 = 4990
23 + 4967 = 4990
47 + 4943 = 4990
53 + 4937 = 4990
59 + 4931 = 4990
71 + 4919 = 4990
101 + 4889 = 4990

Showing the first eight; more decompositions exist.
