Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742738, here are decompositions:

  • 61 + 8742677 = 8742738
  • 101 + 8742637 = 8742738
  • 167 + 8742571 = 8742738
  • 197 + 8742541 = 8742738
  • 227 + 8742511 = 8742738
  • 239 + 8742499 = 8742738
  • 241 + 8742497 = 8742738
  • 269 + 8742469 = 8742738

Showing the first eight; more decompositions exist.
