Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548242, here are decompositions:

  • 109 + 31548133 = 31548242
  • 139 + 31548103 = 31548242
  • 163 + 31548079 = 31548242
  • 211 + 31548031 = 31548242
  • 283 + 31547959 = 31548242
  • 409 + 31547833 = 31548242
  • 541 + 31547701 = 31548242
  • 571 + 31547671 = 31548242

Showing the first eight; more decompositions exist.
