Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10242, here are decompositions:

  • 19 + 10223 = 10242
  • 31 + 10211 = 10242
  • 61 + 10181 = 10242
  • 73 + 10169 = 10242
  • 79 + 10163 = 10242
  • 83 + 10159 = 10242
  • 101 + 10141 = 10242
  • 103 + 10139 = 10242

Showing the first eight; more decompositions exist.
