Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504726, here are decompositions:

  • 23 + 31504703 = 31504726
  • 59 + 31504667 = 31504726
  • 107 + 31504619 = 31504726
  • 179 + 31504547 = 31504726
  • 233 + 31504493 = 31504726
  • 353 + 31504373 = 31504726
  • 359 + 31504367 = 31504726
  • 593 + 31504133 = 31504726

Showing the first eight; more decompositions exist.
