Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544394, here are decompositions:

  • 23 + 31544371 = 31544394
  • 31 + 31544363 = 31544394
  • 47 + 31544347 = 31544394
  • 71 + 31544323 = 31544394
  • 83 + 31544311 = 31544394
  • 97 + 31544297 = 31544394
  • 113 + 31544281 = 31544394
  • 173 + 31544221 = 31544394

Showing the first eight; more decompositions exist.
