Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551082, here are decompositions:

13 + 551069 = 551082
19 + 551063 = 551082
23 + 551059 = 551082
43 + 551039 = 551082
79 + 551003 = 551082
89 + 550993 = 551082
109 + 550973 = 551082
113 + 550969 = 551082

Showing the first eight; more decompositions exist.
