Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547246, here are decompositions:

37 + 31547209 = 31547246
43 + 31547203 = 31547246
103 + 31547143 = 31547246
277 + 31546969 = 31547246
337 + 31546909 = 31547246
433 + 31546813 = 31547246
439 + 31546807 = 31547246
457 + 31546789 = 31547246

Showing the first eight; more decompositions exist.
