Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750642, here are decompositions:

  • 3 + 8750639 = 8750642
  • 151 + 8750491 = 8750642
  • 163 + 8750479 = 8750642
  • 349 + 8750293 = 8750642
  • 409 + 8750233 = 8750642
  • 541 + 8750101 = 8750642
  • 631 + 8750011 = 8750642
  • 661 + 8749981 = 8750642

Showing the first eight; more decompositions exist.
