Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496260, here are decompositions:

  • 41 + 31496219 = 31496260
  • 137 + 31496123 = 31496260
  • 233 + 31496027 = 31496260
  • 281 + 31495979 = 31496260
  • 311 + 31495949 = 31496260
  • 401 + 31495859 = 31496260
  • 503 + 31495757 = 31496260
  • 569 + 31495691 = 31496260

Showing the first eight; more decompositions exist.
