Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4978, here are decompositions:

5 + 4973 = 4978
11 + 4967 = 4978
41 + 4937 = 4978
47 + 4931 = 4978
59 + 4919 = 4978
89 + 4889 = 4978
101 + 4877 = 4978
107 + 4871 = 4978

Showing the first eight; more decompositions exist.
