Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005802, here are decompositions:

41 + 1005761 = 1005802
101 + 1005701 = 1005802
251 + 1005551 = 1005802
389 + 1005413 = 1005802
431 + 1005371 = 1005802
443 + 1005359 = 1005802
509 + 1005293 = 1005802
563 + 1005239 = 1005802

Showing the first eight; more decompositions exist.
