Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515134, here are decompositions:

  • 61 + 31515073 = 31515134
  • 67 + 31515067 = 31515134
  • 127 + 31515007 = 31515134
  • 223 + 31514911 = 31515134
  • 241 + 31514893 = 31515134
  • 463 + 31514671 = 31515134
  • 601 + 31514533 = 31515134
  • 661 + 31514473 = 31515134

Showing the first eight; more decompositions exist.
