Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052720, here are decompositions:

13 + 1052707 = 1052720
157 + 1052563 = 1052720
241 + 1052479 = 1052720
283 + 1052437 = 1052720
307 + 1052413 = 1052720
421 + 1052299 = 1052720
433 + 1052287 = 1052720
439 + 1052281 = 1052720

Showing the first eight; more decompositions exist.
