Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551906, here are decompositions:

97 + 551809 = 551906
139 + 551767 = 551906
163 + 551743 = 551906
193 + 551713 = 551906
337 + 551569 = 551906
349 + 551557 = 551906
367 + 551539 = 551906
463 + 551443 = 551906

Showing the first eight; more decompositions exist.
