Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748940, here are decompositions:

47 + 8748893 = 8748940
59 + 8748881 = 8748940
113 + 8748827 = 8748940
173 + 8748767 = 8748940
197 + 8748743 = 8748940
227 + 8748713 = 8748940
293 + 8748647 = 8748940
353 + 8748587 = 8748940

Showing the first eight; more decompositions exist.
