Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009558, here are decompositions:

59 + 1009499 = 1009558
71 + 1009487 = 1009558
101 + 1009457 = 1009558
197 + 1009361 = 1009558
239 + 1009319 = 1009558
257 + 1009301 = 1009558
269 + 1009289 = 1009558
311 + 1009247 = 1009558

Showing the first eight; more decompositions exist.
