Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519652, here are decompositions:

  • 193 + 31519459 = 31519652
  • 211 + 31519441 = 31519652
  • 271 + 31519381 = 31519652
  • 331 + 31519321 = 31519652
  • 691 + 31518961 = 31519652
  • 739 + 31518913 = 31519652
  • 859 + 31518793 = 31519652
  • 1051 + 31518601 = 31519652

Showing the first eight; more decompositions exist.
