Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551242, here are decompositions:

11 + 551231 = 551242
23 + 551219 = 551242
113 + 551129 = 551242
149 + 551093 = 551242
173 + 551069 = 551242
179 + 551063 = 551242
239 + 551003 = 551242
269 + 550973 = 551242

Showing the first eight; more decompositions exist.
