Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547426, here are decompositions:

13 + 31547413 = 31547426
109 + 31547317 = 31547426
139 + 31547287 = 31547426
223 + 31547203 = 31547426
283 + 31547143 = 31547426
349 + 31547077 = 31547426
439 + 31546987 = 31547426
457 + 31546969 = 31547426

Showing the first eight; more decompositions exist.
