Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504468, here are decompositions:

  • 29 + 31504439 = 31504468
  • 101 + 31504367 = 31504468
  • 239 + 31504229 = 31504468
  • 431 + 31504037 = 31504468
  • 491 + 31503977 = 31504468
  • 557 + 31503911 = 31504468
  • 659 + 31503809 = 31504468
  • 719 + 31503749 = 31504468

Showing the first eight; more decompositions exist.
