Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541874, here are decompositions:

5 + 31541869 = 31541874
17 + 31541857 = 31541874
47 + 31541827 = 31541874
113 + 31541761 = 31541874
137 + 31541737 = 31541874
167 + 31541707 = 31541874
181 + 31541693 = 31541874
197 + 31541677 = 31541874

Showing the first eight; more decompositions exist.
