Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049380, here are decompositions:

41 + 1049339 = 1049380
47 + 1049333 = 1049380
83 + 1049297 = 1049380
179 + 1049201 = 1049380
197 + 1049183 = 1049380
239 + 1049141 = 1049380
251 + 1049129 = 1049380
263 + 1049117 = 1049380

Showing the first eight; more decompositions exist.
