Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455076, here are decompositions:

  • 5 + 31455071 = 31455076
  • 167 + 31454909 = 31455076
  • 173 + 31454903 = 31455076
  • 239 + 31454837 = 31455076
  • 293 + 31454783 = 31455076
  • 449 + 31454627 = 31455076
  • 563 + 31454513 = 31455076
  • 593 + 31454483 = 31455076

Showing the first eight; more decompositions exist.
