Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031390, here are decompositions:

43 + 1031347 = 1031390
67 + 1031323 = 1031390
109 + 1031281 = 1031390
229 + 1031161 = 1031390
271 + 1031119 = 1031390
337 + 1031053 = 1031390
397 + 1030993 = 1031390
433 + 1030957 = 1031390

Showing the first eight; more decompositions exist.
