Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735978, here are decompositions:

7 + 8735971 = 8735978
37 + 8735941 = 8735978
127 + 8735851 = 8735978
151 + 8735827 = 8735978
157 + 8735821 = 8735978
397 + 8735581 = 8735978
421 + 8735557 = 8735978
499 + 8735479 = 8735978

Showing the first eight; more decompositions exist.
