Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544318, here are decompositions:

  • 7 + 31544311 = 31544318
  • 37 + 31544281 = 31544318
  • 97 + 31544221 = 31544318
  • 139 + 31544179 = 31544318
  • 151 + 31544167 = 31544318
  • 229 + 31544089 = 31544318
  • 241 + 31544077 = 31544318
  • 277 + 31544041 = 31544318

Showing the first eight; more decompositions exist.
