Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489444, here are decompositions:

  • 11 + 31489433 = 31489444
  • 17 + 31489427 = 31489444
  • 53 + 31489391 = 31489444
  • 197 + 31489247 = 31489444
  • 227 + 31489217 = 31489444
  • 251 + 31489193 = 31489444
  • 263 + 31489181 = 31489444
  • 347 + 31489097 = 31489444

Showing the first eight; more decompositions exist.
