Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551506, here are decompositions:

3 + 551503 = 551506
17 + 551489 = 551506
23 + 551483 = 551506
83 + 551423 = 551506
167 + 551339 = 551506
443 + 551063 = 551506
467 + 551039 = 551506
479 + 551027 = 551506

Showing the first eight; more decompositions exist.
