Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576214, here are decompositions:

  • 3 + 31576211 = 31576214
  • 13 + 31576201 = 31576214
  • 97 + 31576117 = 31576214
  • 127 + 31576087 = 31576214
  • 211 + 31576003 = 31576214
  • 223 + 31575991 = 31576214
  • 277 + 31575937 = 31576214
  • 337 + 31575877 = 31576214

Showing the first eight; more decompositions exist.
