Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605964, here are decompositions:

  • 11 + 31605953 = 31605964
  • 191 + 31605773 = 31605964
  • 251 + 31605713 = 31605964
  • 263 + 31605701 = 31605964
  • 521 + 31605443 = 31605964
  • 557 + 31605407 = 31605964
  • 563 + 31605401 = 31605964
  • 587 + 31605377 = 31605964

Showing the first eight; more decompositions exist.
