Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551804, here are decompositions:

3 + 551801 = 551804
31 + 551773 = 551804
37 + 551767 = 551804
61 + 551743 = 551804
73 + 551731 = 551804
151 + 551653 = 551804
223 + 551581 = 551804
397 + 551407 = 551804

Showing the first eight; more decompositions exist.
