Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455576, here are decompositions:

  • 43 + 31455533 = 31455576
  • 73 + 31455503 = 31455576
  • 127 + 31455449 = 31455576
  • 149 + 31455427 = 31455576
  • 157 + 31455419 = 31455576
  • 167 + 31455409 = 31455576
  • 179 + 31455397 = 31455576
  • 263 + 31455313 = 31455576

Showing the first eight; more decompositions exist.
