Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551372, here are decompositions:

61 + 551311 = 551372
103 + 551269 = 551372
139 + 551233 = 551372
193 + 551179 = 551372
229 + 551143 = 551372
313 + 551059 = 551372
379 + 550993 = 551372
421 + 550951 = 551372

Showing the first eight; more decompositions exist.
