Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551370, here are decompositions:

7 + 551363 = 551370
23 + 551347 = 551370
31 + 551339 = 551370
59 + 551311 = 551370
73 + 551297 = 551370
89 + 551281 = 551370
101 + 551269 = 551370
137 + 551233 = 551370

Showing the first eight; more decompositions exist.
