Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748130, here are decompositions:

113 + 8748017 = 8748130
173 + 8747957 = 8748130
197 + 8747933 = 8748130
227 + 8747903 = 8748130
239 + 8747891 = 8748130
311 + 8747819 = 8748130
353 + 8747777 = 8748130
383 + 8747747 = 8748130

Showing the first eight; more decompositions exist.
