Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541834, here are decompositions:

7 + 31541827 = 31541834
73 + 31541761 = 31541834
97 + 31541737 = 31541834
127 + 31541707 = 31541834
157 + 31541677 = 31541834
223 + 31541611 = 31541834
271 + 31541563 = 31541834
277 + 31541557 = 31541834

Showing the first eight; more decompositions exist.
