Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 552390, here are decompositions:

11 + 552379 = 552390
37 + 552353 = 552390
73 + 552317 = 552390
89 + 552301 = 552390
107 + 552283 = 552390
127 + 552263 = 552390
131 + 552259 = 552390
149 + 552241 = 552390

Showing the first eight; more decompositions exist.
