Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029278, here are decompositions:

31 + 1029247 = 1029278
79 + 1029199 = 1029278
127 + 1029151 = 1029278
139 + 1029139 = 1029278
241 + 1029037 = 1029278
277 + 1029001 = 1029278
337 + 1028941 = 1029278
541 + 1028737 = 1029278

Showing the first eight; more decompositions exist.
