Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551502, here are decompositions:

13 + 551489 = 551502
19 + 551483 = 551502
41 + 551461 = 551502
59 + 551443 = 551502
79 + 551423 = 551502
139 + 551363 = 551502
163 + 551339 = 551502
181 + 551321 = 551502

Showing the first eight; more decompositions exist.
