Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022242, here are decompositions:

5 + 1022237 = 1022242
41 + 1022201 = 1022242
59 + 1022183 = 1022242
101 + 1022141 = 1022242
113 + 1022129 = 1022242
269 + 1021973 = 1022242
281 + 1021961 = 1022242
443 + 1021799 = 1022242

Showing the first eight; more decompositions exist.
