Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737864, here are decompositions:

101 + 8737763 = 8737864
167 + 8737697 = 8737864
197 + 8737667 = 8737864
281 + 8737583 = 8737864
293 + 8737571 = 8737864
383 + 8737481 = 8737864
431 + 8737433 = 8737864
491 + 8737373 = 8737864

Showing the first eight; more decompositions exist.
