Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619438, here are decompositions:

  • 5 + 8619433 = 8619438
  • 7 + 8619431 = 8619438
  • 11 + 8619427 = 8619438
  • 17 + 8619421 = 8619438
  • 41 + 8619397 = 8619438
  • 197 + 8619241 = 8619438
  • 227 + 8619211 = 8619438
  • 239 + 8619199 = 8619438

Showing the first eight; more decompositions exist.
