Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551526, here are decompositions:

7 + 551519 = 551526
23 + 551503 = 551526
37 + 551489 = 551526
43 + 551483 = 551526
83 + 551443 = 551526
103 + 551423 = 551526
139 + 551387 = 551526
163 + 551363 = 551526

Showing the first eight; more decompositions exist.
