Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642590, here are decompositions:

  • 23 + 8642567 = 8642590
  • 71 + 8642519 = 8642590
  • 83 + 8642507 = 8642590
  • 101 + 8642489 = 8642590
  • 137 + 8642453 = 8642590
  • 353 + 8642237 = 8642590
  • 401 + 8642189 = 8642590
  • 431 + 8642159 = 8642590

Showing the first eight; more decompositions exist.
