Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84878, here are decompositions:

7 + 84871 = 84878
19 + 84859 = 84878
67 + 84811 = 84878
127 + 84751 = 84878
181 + 84697 = 84878
229 + 84649 = 84878
379 + 84499 = 84878
397 + 84481 = 84878

Showing the first eight; more decompositions exist.
