Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82978, here are decompositions:

89 + 82889 = 82978
131 + 82847 = 82978
167 + 82811 = 82978
179 + 82799 = 82978
191 + 82787 = 82978
197 + 82781 = 82978
251 + 82727 = 82978
257 + 82721 = 82978

Showing the first eight; more decompositions exist.
