Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4078, here are decompositions:

  • 5 + 4073 = 4078
  • 29 + 4049 = 4078
  • 59 + 4019 = 4078
  • 71 + 4007 = 4078
  • 89 + 3989 = 4078
  • 131 + 3947 = 4078
  • 149 + 3929 = 4078
  • 167 + 3911 = 4078

Showing the first eight; more decompositions exist.
