Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57978, here are decompositions:

5 + 57973 = 57978
31 + 57947 = 57978
61 + 57917 = 57978
79 + 57899 = 57978
97 + 57881 = 57978
131 + 57847 = 57978
139 + 57839 = 57978
149 + 57829 = 57978

Showing the first eight; more decompositions exist.
