Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544654, here are decompositions:

  • 67 + 31544587 = 31544654
  • 103 + 31544551 = 31544654
  • 283 + 31544371 = 31544654
  • 307 + 31544347 = 31544654
  • 331 + 31544323 = 31544654
  • 373 + 31544281 = 31544654
  • 433 + 31544221 = 31544654
  • 487 + 31544167 = 31544654

Showing the first eight; more decompositions exist.
