Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550780, here are decompositions:

17 + 550763 = 550780
23 + 550757 = 550780
47 + 550733 = 550780
59 + 550721 = 550780
89 + 550691 = 550780
101 + 550679 = 550780
149 + 550631 = 550780
173 + 550607 = 550780

Showing the first eight; more decompositions exist.
