Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555158, here are decompositions:

61 + 555097 = 555158
67 + 555091 = 555158
181 + 554977 = 555158
199 + 554959 = 555158
271 + 554887 = 555158
337 + 554821 = 555158
367 + 554791 = 555158
379 + 554779 = 555158

Showing the first eight; more decompositions exist.
