Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748938, here are decompositions:

61 + 8748877 = 8748938
97 + 8748841 = 8748938
127 + 8748811 = 8748938
151 + 8748787 = 8748938
199 + 8748739 = 8748938
229 + 8748709 = 8748938
337 + 8748601 = 8748938
349 + 8748589 = 8748938

Showing the first eight; more decompositions exist.
