Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527832, here are decompositions:

3 + 31527829 = 31527832
5 + 31527827 = 31527832
131 + 31527701 = 31527832
173 + 31527659 = 31527832
263 + 31527569 = 31527832
311 + 31527521 = 31527832
419 + 31527413 = 31527832
443 + 31527389 = 31527832

Showing the first eight; more decompositions exist.
