Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678394, here are decompositions:

  • 31 + 8678363 = 8678394
  • 41 + 8678353 = 8678394
  • 61 + 8678333 = 8678394
  • 71 + 8678323 = 8678394
  • 83 + 8678311 = 8678394
  • 157 + 8678237 = 8678394
  • 181 + 8678213 = 8678394
  • 191 + 8678203 = 8678394

Showing the first eight; more decompositions exist.
