Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524766, here are decompositions:

  • 3 + 31524763 = 31524766
  • 89 + 31524677 = 31524766
  • 179 + 31524587 = 31524766
  • 197 + 31524569 = 31524766
  • 233 + 31524533 = 31524766
  • 257 + 31524509 = 31524766
  • 347 + 31524419 = 31524766
  • 509 + 31524257 = 31524766

Showing the first eight; more decompositions exist.
