Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544258, here are decompositions:

  • 37 + 31544221 = 31544258
  • 79 + 31544179 = 31544258
  • 127 + 31544131 = 31544258
  • 181 + 31544077 = 31544258
  • 271 + 31543987 = 31544258
  • 331 + 31543927 = 31544258
  • 547 + 31543711 = 31544258
  • 727 + 31543531 = 31544258

Showing the first eight; more decompositions exist.
