Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748398, here are decompositions:

31 + 8748367 = 8748398
37 + 8748361 = 8748398
67 + 8748331 = 8748398
199 + 8748199 = 8748398
367 + 8748031 = 8748398
397 + 8748001 = 8748398
457 + 8747941 = 8748398
541 + 8747857 = 8748398

Showing the first eight; more decompositions exist.
