Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524544, here are decompositions:

  • 3 + 31524541 = 31524544
  • 11 + 31524533 = 31524544
  • 251 + 31524293 = 31524544
  • 347 + 31524197 = 31524544
  • 383 + 31524161 = 31524544
  • 521 + 31524023 = 31524544
  • 743 + 31523801 = 31524544
  • 911 + 31523633 = 31524544

Showing the first eight; more decompositions exist.
