Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550488, here are decompositions:

17 + 550471 = 550488
19 + 550469 = 550488
31 + 550457 = 550488
41 + 550447 = 550488
47 + 550441 = 550488
61 + 550427 = 550488
109 + 550379 = 550488
137 + 550351 = 550488

Showing the first eight; more decompositions exist.
