Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498816, here are decompositions:

  • 3 + 31498813 = 31498816
  • 5 + 31498811 = 31498816
  • 53 + 31498763 = 31498816
  • 113 + 31498703 = 31498816
  • 257 + 31498559 = 31498816
  • 269 + 31498547 = 31498816
  • 317 + 31498499 = 31498816
  • 347 + 31498469 = 31498816

Showing the first eight; more decompositions exist.
