Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555804, here are decompositions:

37 + 555767 = 555804
43 + 555761 = 555804
61 + 555743 = 555804
97 + 555707 = 555804
107 + 555697 = 555804
113 + 555691 = 555804
127 + 555677 = 555804
167 + 555637 = 555804

Showing the first eight; more decompositions exist.
