Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447126, here are decompositions:

  • 23 + 31447103 = 31447126
  • 47 + 31447079 = 31447126
  • 83 + 31447043 = 31447126
  • 107 + 31447019 = 31447126
  • 173 + 31446953 = 31447126
  • 233 + 31446893 = 31447126
  • 383 + 31446743 = 31447126
  • 563 + 31446563 = 31447126

Showing the first eight; more decompositions exist.
