Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624436, here are decompositions:

  • 7 + 31624429 = 31624436
  • 13 + 31624423 = 31624436
  • 73 + 31624363 = 31624436
  • 79 + 31624357 = 31624436
  • 97 + 31624339 = 31624436
  • 307 + 31624129 = 31624436
  • 367 + 31624069 = 31624436
  • 433 + 31624003 = 31624436

Showing the first eight; more decompositions exist.
