Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472044, here are decompositions:

  • 3 + 31472041 = 31472044
  • 41 + 31472003 = 31472044
  • 53 + 31471991 = 31472044
  • 137 + 31471907 = 31472044
  • 257 + 31471787 = 31472044
  • 281 + 31471763 = 31472044
  • 347 + 31471697 = 31472044
  • 467 + 31471577 = 31472044

Showing the first eight; more decompositions exist.
