Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551642, here are decompositions:

61 + 551581 = 551642
73 + 551569 = 551642
103 + 551539 = 551642
139 + 551503 = 551642
181 + 551461 = 551642
199 + 551443 = 551642
331 + 551311 = 551642
373 + 551269 = 551642

Showing the first eight; more decompositions exist.
