Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637830, here are decompositions:

  • 43 + 8637787 = 8637830
  • 163 + 8637667 = 8637830
  • 193 + 8637637 = 8637830
  • 211 + 8637619 = 8637830
  • 307 + 8637523 = 8637830
  • 337 + 8637493 = 8637830
  • 349 + 8637481 = 8637830
  • 379 + 8637451 = 8637830

Showing the first eight; more decompositions exist.
