Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055278, here are decompositions:

11 + 1055267 = 1055278
17 + 1055261 = 1055278
47 + 1055231 = 1055278
89 + 1055189 = 1055278
137 + 1055141 = 1055278
239 + 1055039 = 1055278
347 + 1054931 = 1055278
509 + 1054769 = 1055278

Showing the first eight; more decompositions exist.
