Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001782, here are decompositions:

59 + 1001723 = 1001782
113 + 1001669 = 1001782
233 + 1001549 = 1001782
251 + 1001531 = 1001782
281 + 1001501 = 1001782
401 + 1001381 = 1001782
461 + 1001321 = 1001782
479 + 1001303 = 1001782

Showing the first eight; more decompositions exist.
