Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697472, here are decompositions:

83 + 8697389 = 8697472
233 + 8697239 = 8697472
239 + 8697233 = 8697472
359 + 8697113 = 8697472
383 + 8697089 = 8697472
479 + 8696993 = 8697472
521 + 8696951 = 8697472
569 + 8696903 = 8697472

Showing the first eight; more decompositions exist.
