Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550642, here are decompositions:

5 + 550637 = 550642
11 + 550631 = 550642
89 + 550553 = 550642
101 + 550541 = 550642
173 + 550469 = 550642
263 + 550379 = 550642
353 + 550289 = 550642
359 + 550283 = 550642

Showing the first eight; more decompositions exist.
