Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84978, here are decompositions:

11 + 84967 = 84978
17 + 84961 = 84978
31 + 84947 = 84978
59 + 84919 = 84978
107 + 84871 = 84978
109 + 84869 = 84978
151 + 84827 = 84978
167 + 84811 = 84978

Showing the first eight; more decompositions exist.
