Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84278, here are decompositions:

31 + 84247 = 84278
67 + 84211 = 84278
79 + 84199 = 84278
97 + 84181 = 84278
151 + 84127 = 84278
157 + 84121 = 84278
211 + 84067 = 84278
367 + 83911 = 84278

Showing the first eight; more decompositions exist.
