Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746238, here are decompositions:

31 + 8746207 = 8746238
229 + 8746009 = 8746238
349 + 8745889 = 8746238
409 + 8745829 = 8746238
421 + 8745817 = 8746238
439 + 8745799 = 8746238
541 + 8745697 = 8746238
601 + 8745637 = 8746238

Showing the first eight; more decompositions exist.
