Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551744, here are decompositions:

13 + 551731 = 551744
31 + 551713 = 551744
73 + 551671 = 551744
157 + 551587 = 551744
163 + 551581 = 551744
241 + 551503 = 551744
283 + 551461 = 551744
337 + 551407 = 551744

Showing the first eight; more decompositions exist.
