Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452904, here are decompositions:

  • 3 + 31452901 = 31452904
  • 53 + 31452851 = 31452904
  • 101 + 31452803 = 31452904
  • 173 + 31452731 = 31452904
  • 227 + 31452677 = 31452904
  • 281 + 31452623 = 31452904
  • 317 + 31452587 = 31452904
  • 383 + 31452521 = 31452904

Showing the first eight; more decompositions exist.
