Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749238, here are decompositions:

19 + 8749219 = 8749238
31 + 8749207 = 8749238
97 + 8749141 = 8749238
151 + 8749087 = 8749238
349 + 8748889 = 8749238
397 + 8748841 = 8749238
499 + 8748739 = 8749238
739 + 8748499 = 8749238

Showing the first eight; more decompositions exist.
