Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541934, here are decompositions:

31 + 31541903 = 31541934
41 + 31541893 = 31541934
43 + 31541891 = 31541934
107 + 31541827 = 31541934
173 + 31541761 = 31541934
197 + 31541737 = 31541934
227 + 31541707 = 31541934
241 + 31541693 = 31541934

Showing the first eight; more decompositions exist.
