Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055380, here are decompositions:

17 + 1055363 = 1055380
59 + 1055321 = 1055380
113 + 1055267 = 1055380
149 + 1055231 = 1055380
191 + 1055189 = 1055380
239 + 1055141 = 1055380
317 + 1055063 = 1055380
449 + 1054931 = 1055380

Showing the first eight; more decompositions exist.
