Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697938, here are decompositions:

19 + 8697919 = 8697938
37 + 8697901 = 8697938
79 + 8697859 = 8697938
127 + 8697811 = 8697938
241 + 8697697 = 8697938
331 + 8697607 = 8697938
439 + 8697499 = 8697938
661 + 8697277 = 8697938

Showing the first eight; more decompositions exist.
