Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480488, here are decompositions:

  • 47 + 31480441 = 31480488
  • 97 + 31480391 = 31480488
  • 107 + 31480381 = 31480488
  • 139 + 31480349 = 31480488
  • 199 + 31480289 = 31480488
  • 229 + 31480259 = 31480488
  • 359 + 31480129 = 31480488
  • 397 + 31480091 = 31480488

Showing the first eight; more decompositions exist.
