Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546242, here are decompositions:

  • 11 + 31546231 = 31546242
  • 43 + 31546199 = 31546242
  • 61 + 31546181 = 31546242
  • 83 + 31546159 = 31546242
  • 89 + 31546153 = 31546242
  • 113 + 31546129 = 31546242
  • 131 + 31546111 = 31546242
  • 173 + 31546069 = 31546242

Showing the first eight; more decompositions exist.
