Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526738, here are decompositions:

  • 7 + 31526731 = 31526738
  • 211 + 31526527 = 31526738
  • 241 + 31526497 = 31526738
  • 307 + 31526431 = 31526738
  • 349 + 31526389 = 31526738
  • 367 + 31526371 = 31526738
  • 379 + 31526359 = 31526738
  • 421 + 31526317 = 31526738

Showing the first eight; more decompositions exist.
