Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551142, here are decompositions:

13 + 551129 = 551142
29 + 551113 = 551142
43 + 551099 = 551142
73 + 551069 = 551142
79 + 551063 = 551142
83 + 551059 = 551142
103 + 551039 = 551142
139 + 551003 = 551142

Showing the first eight; more decompositions exist.
