Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551158, here are decompositions:

29 + 551129 = 551158
59 + 551099 = 551158
89 + 551069 = 551158
131 + 551027 = 551158
197 + 550961 = 551158
317 + 550841 = 551158
347 + 550811 = 551158
401 + 550757 = 551158

Showing the first eight; more decompositions exist.
