Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551750, here are decompositions:

7 + 551743 = 551750
19 + 551731 = 551750
37 + 551713 = 551750
61 + 551689 = 551750
79 + 551671 = 551750
97 + 551653 = 551750
163 + 551587 = 551750
181 + 551569 = 551750

Showing the first eight; more decompositions exist.
