Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052642, here are decompositions:

13 + 1052629 = 1052642
79 + 1052563 = 1052642
109 + 1052533 = 1052642
163 + 1052479 = 1052642
211 + 1052431 = 1052642
229 + 1052413 = 1052642
313 + 1052329 = 1052642
373 + 1052269 = 1052642

Showing the first eight; more decompositions exist.
