Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464530, here are decompositions:

  • 37 + 31464493 = 31464530
  • 67 + 31464463 = 31464530
  • 79 + 31464451 = 31464530
  • 103 + 31464427 = 31464530
  • 109 + 31464421 = 31464530
  • 337 + 31464193 = 31464530
  • 463 + 31464067 = 31464530
  • 499 + 31464031 = 31464530

Showing the first eight; more decompositions exist.
