Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551202, here are decompositions:

5 + 551197 = 551202
23 + 551179 = 551202
59 + 551143 = 551202
73 + 551129 = 551202
89 + 551113 = 551202
103 + 551099 = 551202
109 + 551093 = 551202
139 + 551063 = 551202

Showing the first eight; more decompositions exist.
