Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551264, here are decompositions:

31 + 551233 = 551264
67 + 551197 = 551264
151 + 551113 = 551264
157 + 551107 = 551264
271 + 550993 = 551264
313 + 550951 = 551264
421 + 550843 = 551264
433 + 550831 = 551264

Showing the first eight; more decompositions exist.
