Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752978, here are decompositions:

107 + 8752871 = 8752978
131 + 8752847 = 8752978
197 + 8752781 = 8752978
281 + 8752697 = 8752978
359 + 8752619 = 8752978
467 + 8752511 = 8752978
557 + 8752421 = 8752978
599 + 8752379 = 8752978

Showing the first eight; more decompositions exist.
