Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40212, here are decompositions:

  • 19 + 40193 = 40212
  • 23 + 40189 = 40212
  • 43 + 40169 = 40212
  • 59 + 40153 = 40212
  • 61 + 40151 = 40212
  • 83 + 40129 = 40212
  • 89 + 40123 = 40212
  • 101 + 40111 = 40212

Showing the first eight; more decompositions exist.
