Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550520, here are decompositions:

7 + 550513 = 550520
31 + 550489 = 550520
73 + 550447 = 550520
79 + 550441 = 550520
151 + 550369 = 550520
211 + 550309 = 550520
241 + 550279 = 550520
307 + 550213 = 550520

Showing the first eight; more decompositions exist.
