Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931558, here are decompositions:

29 + 931529 = 931558
41 + 931517 = 931558
59 + 931499 = 931558
71 + 931487 = 931558
137 + 931421 = 931558
239 + 931319 = 931558
269 + 931289 = 931558
317 + 931241 = 931558

Showing the first eight; more decompositions exist.
