Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484928, here are decompositions:

  • 17 + 31484911 = 31484928
  • 89 + 31484839 = 31484928
  • 107 + 31484821 = 31484928
  • 127 + 31484801 = 31484928
  • 131 + 31484797 = 31484928
  • 151 + 31484777 = 31484928
  • 157 + 31484771 = 31484928
  • 229 + 31484699 = 31484928

Showing the first eight; more decompositions exist.
