Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022278, here are decompositions:

29 + 1022249 = 1022278
41 + 1022237 = 1022278
137 + 1022141 = 1022278
149 + 1022129 = 1022278
317 + 1021961 = 1022278
359 + 1021919 = 1022278
479 + 1021799 = 1022278
617 + 1021661 = 1022278

Showing the first eight; more decompositions exist.
