Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551348, here are decompositions:

37 + 551311 = 551348
67 + 551281 = 551348
79 + 551269 = 551348
151 + 551197 = 551348
241 + 551107 = 551348
331 + 551017 = 551348
379 + 550969 = 551348
397 + 550951 = 551348

Showing the first eight; more decompositions exist.
