Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547394, here are decompositions:

37 + 31547357 = 31547394
97 + 31547297 = 31547394
107 + 31547287 = 31547394
113 + 31547281 = 31547394
127 + 31547267 = 31547394
163 + 31547231 = 31547394
191 + 31547203 = 31547394
233 + 31547161 = 31547394

Showing the first eight; more decompositions exist.
