Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555042, here are decompositions:

13 + 555029 = 555042
73 + 554969 = 555042
83 + 554959 = 555042
149 + 554893 = 555042
151 + 554891 = 555042
193 + 554849 = 555042
199 + 554843 = 555042
239 + 554803 = 555042

Showing the first eight; more decompositions exist.
