Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498632, here are decompositions:

  • 41 + 31498591 = 31498632
  • 73 + 31498559 = 31498632
  • 83 + 31498549 = 31498632
  • 103 + 31498529 = 31498632
  • 163 + 31498469 = 31498632
  • 211 + 31498421 = 31498632
  • 283 + 31498349 = 31498632
  • 353 + 31498279 = 31498632

Showing the first eight; more decompositions exist.
