Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740830, here are decompositions:

  • 23 + 8740807 = 8740830
  • 31 + 8740799 = 8740830
  • 37 + 8740793 = 8740830
  • 41 + 8740789 = 8740830
  • 47 + 8740783 = 8740830
  • 67 + 8740763 = 8740830
  • 73 + 8740757 = 8740830
  • 103 + 8740727 = 8740830

Showing the first eight; more decompositions exist.
