Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006580, here are decompositions:

37 + 1006543 = 1006580
67 + 1006513 = 1006580
73 + 1006507 = 1006580
109 + 1006471 = 1006580
139 + 1006441 = 1006580
229 + 1006351 = 1006580
241 + 1006339 = 1006580
271 + 1006309 = 1006580

Showing the first eight; more decompositions exist.
