Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478526, here are decompositions:

  • 5 + 31478521 = 31478526
  • 43 + 31478483 = 31478526
  • 47 + 31478479 = 31478526
  • 97 + 31478429 = 31478526
  • 127 + 31478399 = 31478526
  • 137 + 31478389 = 31478526
  • 193 + 31478333 = 31478526
  • 199 + 31478327 = 31478526

Showing the first eight; more decompositions exist.
