Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674578, here are decompositions:

  • 7 + 8674571 = 8674578
  • 41 + 8674537 = 8674578
  • 47 + 8674531 = 8674578
  • 67 + 8674511 = 8674578
  • 79 + 8674499 = 8674578
  • 89 + 8674489 = 8674578
  • 131 + 8674447 = 8674578
  • 179 + 8674399 = 8674578

Showing the first eight; more decompositions exist.
