Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600840, here are decompositions:

97 + 8600743 = 8600840
139 + 8600701 = 8600840
163 + 8600677 = 8600840
211 + 8600629 = 8600840
307 + 8600533 = 8600840
331 + 8600509 = 8600840
349 + 8600491 = 8600840
373 + 8600467 = 8600840

Showing the first eight; more decompositions exist.
