Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4258, here are decompositions:

  • 5 + 4253 = 4258
  • 17 + 4241 = 4258
  • 29 + 4229 = 4258
  • 41 + 4217 = 4258
  • 47 + 4211 = 4258
  • 101 + 4157 = 4258
  • 131 + 4127 = 4258
  • 167 + 4091 = 4258

Showing the first eight; more decompositions exist.
