Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87738, here are decompositions:

  • 17 + 87721 = 87738
  • 19 + 87719 = 87738
  • 37 + 87701 = 87738
  • 41 + 87697 = 87738
  • 47 + 87691 = 87738
  • 59 + 87679 = 87738
  • 67 + 87671 = 87738
  • 89 + 87649 = 87738

Showing the first eight; more decompositions exist.
