Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87278, here are decompositions:

67 + 87211 = 87278
97 + 87181 = 87278
127 + 87151 = 87278
157 + 87121 = 87278
229 + 87049 = 87278
241 + 87037 = 87278
349 + 86929 = 87278
409 + 86869 = 87278

Showing the first eight; more decompositions exist.
