Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534582, here are decompositions:

29 + 31534553 = 31534582
89 + 31534493 = 31534582
239 + 31534343 = 31534582
281 + 31534301 = 31534582
311 + 31534271 = 31534582
383 + 31534199 = 31534582
461 + 31534121 = 31534582
479 + 31534103 = 31534582

Showing the first eight; more decompositions exist.
