Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597978, here are decompositions:

  • 31 + 8597947 = 8597978
  • 139 + 8597839 = 8597978
  • 157 + 8597821 = 8597978
  • 241 + 8597737 = 8597978
  • 271 + 8597707 = 8597978
  • 331 + 8597647 = 8597978
  • 349 + 8597629 = 8597978
  • 379 + 8597599 = 8597978

Showing the first eight; more decompositions exist.
