Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550580, here are decompositions:

3 + 550577 = 550580
61 + 550519 = 550580
67 + 550513 = 550580
109 + 550471 = 550580
139 + 550441 = 550580
211 + 550369 = 550580
229 + 550351 = 550580
271 + 550309 = 550580

Showing the first eight; more decompositions exist.
