Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541544, here are decompositions:

17 + 31541527 = 31541544
37 + 31541507 = 31541544
61 + 31541483 = 31541544
107 + 31541437 = 31541544
127 + 31541417 = 31541544
197 + 31541347 = 31541544
263 + 31541281 = 31541544
277 + 31541267 = 31541544

Showing the first eight; more decompositions exist.
