Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547834, here are decompositions:

103 + 31547731 = 31547834
127 + 31547707 = 31547834
151 + 31547683 = 31547834
163 + 31547671 = 31547834
193 + 31547641 = 31547834
277 + 31547557 = 31547834
421 + 31547413 = 31547834
547 + 31547287 = 31547834

Showing the first eight; more decompositions exist.
