Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555900, here are decompositions:

29 + 555871 = 555900
43 + 555857 = 555900
47 + 555853 = 555900
71 + 555829 = 555900
73 + 555827 = 555900
139 + 555761 = 555900
157 + 555743 = 555900
193 + 555707 = 555900

Showing the first eight; more decompositions exist.
