Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582932, here are decompositions:

19 + 31582913 = 31582932
41 + 31582891 = 31582932
109 + 31582823 = 31582932
113 + 31582819 = 31582932
151 + 31582781 = 31582932
193 + 31582739 = 31582932
331 + 31582601 = 31582932
373 + 31582559 = 31582932

Showing the first eight; more decompositions exist.
