Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474358, here are decompositions:

  • 7 + 31474351 = 31474358
  • 67 + 31474291 = 31474358
  • 109 + 31474249 = 31474358
  • 229 + 31474129 = 31474358
  • 367 + 31473991 = 31474358
  • 457 + 31473901 = 31474358
  • 547 + 31473811 = 31474358
  • 577 + 31473781 = 31474358

Showing the first eight; more decompositions exist.
