Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541766, here are decompositions:

5 + 31541761 = 31541766
29 + 31541737 = 31541766
59 + 31541707 = 31541766
73 + 31541693 = 31541766
89 + 31541677 = 31541766
107 + 31541659 = 31541766
197 + 31541569 = 31541766
239 + 31541527 = 31541766

Showing the first eight; more decompositions exist.
