Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527850, here are decompositions:

23 + 31527827 = 31527850
149 + 31527701 = 31527850
173 + 31527677 = 31527850
191 + 31527659 = 31527850
281 + 31527569 = 31527850
317 + 31527533 = 31527850
353 + 31527497 = 31527850
359 + 31527491 = 31527850

Showing the first eight; more decompositions exist.
