Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541844, here are decompositions:

17 + 31541827 = 31541844
83 + 31541761 = 31541844
107 + 31541737 = 31541844
137 + 31541707 = 31541844
151 + 31541693 = 31541844
167 + 31541677 = 31541844
193 + 31541651 = 31541844
211 + 31541633 = 31541844

Showing the first eight; more decompositions exist.
