Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749388, here are decompositions:

31 + 8749357 = 8749388
79 + 8749309 = 8749388
181 + 8749207 = 8749388
397 + 8748991 = 8749388
409 + 8748979 = 8749388
499 + 8748889 = 8749388
541 + 8748847 = 8749388
547 + 8748841 = 8749388

Showing the first eight; more decompositions exist.
