Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547336, here are decompositions:

19 + 31547317 = 31547336
127 + 31547209 = 31547336
193 + 31547143 = 31547336
349 + 31546987 = 31547336
367 + 31546969 = 31547336
523 + 31546813 = 31547336
547 + 31546789 = 31547336
577 + 31546759 = 31547336

Showing the first eight; more decompositions exist.
