Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007278, here are decompositions:

29 + 1007249 = 1007278
47 + 1007231 = 1007278
149 + 1007129 = 1007278
179 + 1007099 = 1007278
197 + 1007081 = 1007278
257 + 1007021 = 1007278
401 + 1006877 = 1007278
431 + 1006847 = 1007278

Showing the first eight; more decompositions exist.
