Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029442, here are decompositions:

59 + 1029383 = 1029442
83 + 1029359 = 1029442
101 + 1029341 = 1029442
179 + 1029263 = 1029442
191 + 1029251 = 1029442
233 + 1029209 = 1029442
251 + 1029191 = 1029442
263 + 1029179 = 1029442

Showing the first eight; more decompositions exist.
