Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558188, here are decompositions:

67 + 558121 = 558188
79 + 558109 = 558188
97 + 558091 = 558188
181 + 558007 = 558188
331 + 557857 = 558188
409 + 557779 = 558188
457 + 557731 = 558188
577 + 557611 = 558188

Showing the first eight; more decompositions exist.
