Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021368, here are decompositions:

37 + 1021331 = 1021368
41 + 1021327 = 1021368
67 + 1021301 = 1021368
71 + 1021297 = 1021368
79 + 1021289 = 1021368
97 + 1021271 = 1021368
107 + 1021261 = 1021368
109 + 1021259 = 1021368

Showing the first eight; more decompositions exist.
