Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527544, here are decompositions:

  • 3 + 31527541 = 31527544
  • 11 + 31527533 = 31527544
  • 23 + 31527521 = 31527544
  • 47 + 31527497 = 31527544
  • 53 + 31527491 = 31527544
  • 131 + 31527413 = 31527544
  • 137 + 31527407 = 31527544
  • 227 + 31527317 = 31527544

Showing the first eight; more decompositions exist.
