Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551394, here are decompositions:

7 + 551387 = 551394
13 + 551381 = 551394
31 + 551363 = 551394
47 + 551347 = 551394
73 + 551321 = 551394
83 + 551311 = 551394
97 + 551297 = 551394
113 + 551281 = 551394

Showing the first eight; more decompositions exist.
