Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000278, here are decompositions:

5 + 1000273 = 1000278
29 + 1000249 = 1000278
47 + 1000231 = 1000278
67 + 1000211 = 1000278
79 + 1000199 = 1000278
107 + 1000171 = 1000278
127 + 1000151 = 1000278
157 + 1000121 = 1000278

Showing the first eight; more decompositions exist.
