Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652778, here are decompositions:

  • 5 + 8652773 = 8652778
  • 11 + 8652767 = 8652778
  • 47 + 8652731 = 8652778
  • 131 + 8652647 = 8652778
  • 137 + 8652641 = 8652778
  • 149 + 8652629 = 8652778
  • 191 + 8652587 = 8652778
  • 227 + 8652551 = 8652778

Showing the first eight; more decompositions exist.
