Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023812, here are decompositions:

43 + 1023769 = 1023812
61 + 1023751 = 1023812
79 + 1023733 = 1023812
211 + 1023601 = 1023812
241 + 1023571 = 1023812
271 + 1023541 = 1023812
313 + 1023499 = 1023812
421 + 1023391 = 1023812

Showing the first eight; more decompositions exist.
