Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555810, here are decompositions:

43 + 555767 = 555810
67 + 555743 = 555810
71 + 555739 = 555810
103 + 555707 = 555810
113 + 555697 = 555810
127 + 555683 = 555810
139 + 555671 = 555810
149 + 555661 = 555810

Showing the first eight; more decompositions exist.
